CB500 Honda by Duke Motorcycles

When tackling a custom build, there are a wide variety of approaches available to the craftsman. From extravagant to austere, there is no right way to create art. In the case of the Duke Motorcycles Honda CB500 Four Café Racer, Frenchman Lionel Duke chose to keep it clean, building a chassis around a classic 1970s inline-4 powerplant.

Although the powerplant is easily recognizable as an air-cooled four-cylinder Honda, most people would expect the more iconic CB400 or CB750 Fours in a café racer. Instead, Duke went with the less-heralded middle child. That, of course, is hardly the point of the build, and the motor was kept relatively stock. Instead, the Duke Motorcycles Honda CB500 Four Café Racer is all about minimalism and a striking chassis.

To give the build undisputed café racer credibility, the Duke CB500 gets thoroughly modern suspension. Despite being painted white, that is an inverted Öhlins fork, a Ducati Panigale single-sided swingarm, and an Öhlins piggyback-reservoir shock. Matching the suspension is high-performance Brembo braking, while Bonamici Racing provided footrests from Central Italy. Retromod, indeed.

Above the chassis is an aluminum tank/seat/tail unit. “It was realized by hand,” Duke says. “I wanted to keep the proportion of the tank and form of the original so that one recognizes the CB500.” The tank also houses a retro-modern Motogadget MST Speedster analog/digital speedometer.

The tank is adorned with a #7, as is the headlight and the aluminum front fender. “I engraved the front with a 7 to recall the decoration of the tank,” Duke explains, “the 7 being the symbolic figure that represents the purity. It seemed to me that was connected to the bike.”

Furthering the purity theme, the motorcycle is overwhelmingly white. “The color white, pure white, it’s something that I wanted to do for a long time,” Duke reveals, “a completely white motorcycle with decoration that I made in 18-carat gold leaf.”

For the rear bodywork, I wanted it to be very short to free the rear wheel and give it a racing side.” The seat is covered in Alcantara, which has a microfiber pile that recalls suede. Nice-based NMB Design was responsible for building the seat.

 

 

Throughout the motorcycle are decorative and functional cables. “Stainless steel cables through the length of the bike give it a luxury side,” Duke says, “and a finesse to this preparation.”

 

Four Keihin carburetors are retained to feed the Honda motor, with the velocity stack intakes made in the Mediterranean coastal town of Toulon by USVRacing. The engine was fully restored by Duke Motorcycles for optimum performance and reliability, with the unique touch of a CNC Racing hydraulic clutch from Arezzo, Italy.

While the exhaust retains the four-into-four architecture, there is a substantial twist. Unmuffled, two pipes exit under the seat and another short pair peak out on the right side—both a nod to modern MotoGP designs and made from stainless steel. Speaking of MotoGP, the Duke CB500 sports Michelin Power Slick Evo racing tires.


The Duke Motorcycles Honda CB500 Four Café Racer is a long-time coming in more ways than one. Getting his start customizing a Honda Dax (CT70/Trail 70 in the US), Duke has built dozens of custom motorcycles in preparation for this outstanding result.


Working alone in his Tourrettes-sur-Loup shop 17 miles east of Nice, Duke has spent 700 hours on this motorcycle. “It is a personal project that I wanted deliberately different from what we can see,” he says, “a project that looks like me and that highlights my style and all the methods of work that I use.”

“I have been passionate about motorcycles since the youngest age,” Duke says, “but especially of design and manual construction. I studied mechanics, bodywork, and painting, which really helps me in my work. I’m crazy about music, and design in general. I have a passion for watches, architecture, and supercars.”

 

Often, builders have twinges of regrets and second-guessing when they are done with their builds. That’s not the case with Duke and his CB500 Four Café Racer. “There is not really a thing that I would change,” he asserts. “It is really as I wanted it, and when I finish a bike, I think about the next one and do not think to modify what is already done. I tried to bring the French touch and maximum finesse of work to create this bike.” An indicator of that French touch is a French flag embedded in the tank, under a screen between two stainless steel cables.

One reason Duke is satisfied with the CB500 Four Café Racer is that he built it for himself, rather than a customer. “With a client, it is a little different,” Duke explains. “I advise him, and I listen to what he wants. When I make a bike for me, I take the opportunity to do new things, show what I am able to do. With a client, we create a thing for two. The difficulty is that clients do not often project themselves. They often want copies seen on the Internet.”

 

Undoubtedly, the Duke Motorcycles Honda CB500 Four Café Racer meets Lionel Duke’s standards for individuality. Likely, though, this striking white motorcycle will have clients of other builders pointing to it for inspiration.

Located between Cannes and Monaco, Duke cane supply you with parts to create something of your taste or a complete build for you to ride home on.

My 4 into 1 is still making people happy after 22 years in business

Well, for 22 years I have been sending my very own 4 into 1 exhaust systems to Customers all over the globe and along the way I have many repeat customers.

I love hearing from them too, as they perform really well throughout the power curve and sound so cool when you get on the loud button.

Alexander Iverson purchased the 4 into 1 system for me and is over the Moon with the look, Fit and of course sound and I am sure that you will be just as happy when you purchase a system from me?

Weekend is here but its going to be damn Hot In Southern California

I know, I know- I should not complain about the weather, but- I left the shores of Blighty back in 1997, this weekend it will be in the 90’s and I am lucky that I now have the Barn to work in, albeit no A/C.  Its surprising how much you can get done when there is a big ball of fire trying to make you evaporate.

Today I shall be packing up quite a few New exhaust systems, with more on the way, busy time of the year for me as people are wrenching on their machines and of course, with warmer temperatures, then riding season is at its most fruitful, I too love riding early in the morning as the warmth of the Sun begins to make the tarmac steam and for me, there is nothing better to clear your head than a crisp morning.

But parts have to be re-stocked and I am trying to get the New Place in some sort of order, so I can pick and pack my parts a little easier and then ship right out to my Customers, I am lucky as the Main Post Office is just down the road, so that means I can take them directly to the Loading dock to scan and load the packages and boxes onto the truck that is going out to deliver.

I am coming up with a few different parts too and this all takes time, but I am enjoying what I do and when you work from your own Workshop with no landlord hassling you, a lot of stress simply disappears.

Happy Sunday everyone and hope you get a little bit of time to be able to do some wrenching on your machine, let me know if I can help by phone or text, 714-598-8392.  keep building and keep riding.

New set of frame Hoops made and banging out other parts too.

Well, time and tide wait for no man, woman or child for that matter, I have been flat out as of late and will be busy for some time to come for sure, albeit in the Barn designing a few different exhausts and parts etc.  Fun times ahead and I hope to try a few different brands of machines as well, a kaleidoscope of colors in parts and a good sprinkling of new tools to help you work on your ride easier.

Many people email all the time carpy@carpyscaferacers.com or at carpysgarage@aol.com with questions on their build and what they can do to get the motorcycle running a little better.  I try and help the best way that I can, I have been doing this for more years than I can remember but we are all a big combustion engine family and, if I can help, I feel great for making someone’s day.

So, today I made a bunch of round steel Flat Frame Hoops, I have sold over 500 of these and needed to make a load more once more as I was almost out of stock, these are all mandrel bent and I make them long, that way you can cut and get the look you require easier.

Tomorrow I shall continue to bang out some of these frame hoops, but this time I shall be bending the versions that have the 22 degree kick up, as I only have 3 of them left in my inventory, so I will be quite busy for some time and hope to be offering a few more parts on the website to help you get your creation on the road.

So stay tuned as there may be a part you are looking for and I make these right here, not in China, not in India and Not in Taiwan, all made in California USA.

I Always want to thank you for ordering from me, I have been running my business here in SoCal for 22 years and it just get more enjoyable every year, I get people come up to me where ever we are in the world and say, hey! Arnt you that guy who builds the bikes in California? I am always blown away by that.  So thank you from the bottom of my heart for sticking with me and my products, it means a lot.

Peace N grease

Kiyo Builds a Triple Engine CB750 Machine for Speed.

Some of you that may be old enough to remember the Legendary Builder and Racer ” Russ Collins” May well indeed remember the triple engin monster of a machine called  “Atchison, Topeka & Santa Fe”, This was named after the famous Rail line and Russ Debuted the bike back in 1973, when I was a mere 11 years old, little did I know I would watch this motorcycle in person and what a great feat of engineering for its time.   Featuring three nitro-burning CB750 engines mounted in tandem, the AT&SF was the first motorcycle to make a seven-second quarter-mile pass (7.80 seconds at 179 mph) at Ontario Motor Speedway in 1973.

The bike not surprisingly, the AT&SF was extraordinarily difficult to ride. A horrendous crash in Akron, Ohio, in 1976 destroyed the motorcycle and left Collins in a wheelchair for months, giving him plenty of free time to contemplate its replacement. It was during this long recuperation he dreamed up “The Sorcerer,” powered by a pair of 1,000cc Honda Fours tied together and tuned to fire like a V-8 then topped with a GMC 3-71 supercharger. The NHRA Top Fuel record that Collins set on the Sorcerer in 1977—7.30 seconds at 199.55 mph—stood unchallenged for more than 11 years. Collins was more than a decade ahead of his time.  But, the machine is now being completely rebuilt and the motors are almost ready once more.

49 Years after that, one of the coolest engineer/Builders has built his own Triple Engined SOHC machine and dreams of hitting the Salt for a record of his very own, Originally from the coastal city of Kumamoto on the Japanese island of Kyushu, Kiyonaga-san opened the Kiyo’s Garage workshop in Gardena, Los Angeles County, back in 2013. Back then Kiyo created a CB750 Custom Machine named “Cherry Blossom” Hand made stretched frame and a ATP Turbo with ARD Magneto. Ran really well at El Mirage dry lake.

 

Kiyos worked at the garage company for over a decade and was Yoshi’s top Mechanic/builder, he learned a lot from Yoshi and decided that it was time for him to get his own workshop in Gardena, so he set up shop in 2013 and has become a prolific quality Builder/Fabricator of Motorcycles.  His second machine was another CB750 Based Creation called ” Gekko ” (it means “moonlight” in Japanese).

Except this time, he linked together two CB750 motors, boring them out for a total capacity of 1,620 cc.Of which he ran at El Mirage and Bonneville on SCTA events.

So to complete the trifecta of Motorcycle and of course Engines, Kiyo decided to go with a trilogy machine that evokes his Japanese heritage with Motorcycles and Manufacturers, as well as his Engineering skills and Custom creativity, thus the “Galaxy” was Born.

The idea of actually building The Galaxy started to materialize when Kiyo and his wife, Kat, visited the Haas Moto Museum in Dallas, Texas, in May, 2019. They were there to discuss the museum’s acquisition of Cherry Blossom and Gekko — but Kiyo also presented the museum’s owner, Bobby Haas, and director, Stacey Mayfield, with sketches of his three-engined concept.

All three of The Galaxy’s four-cylinder power plants are 1978 Honda CB750 units with F2 large port heads. Each motor has been bored out to 836cc, and fully rebuilt with lightened and balanced crankshafts, heavy-duty connecting rods, performance cams and oversized stainless steel valves. Extra care was taken to make sure each motor’s internals conformed to the exact same spec. Each motor is fed by four Keihin FCR 35mm carbs, with significant work to the intake manifolds to help them run optimally. All three carb sets are linked via a rod and heim joint setup to make it easier to synchronize the throttle slider. But re-jetting is still a chore, given that there are 12 carbs to fettle. The entire setup breathes out through twelve custom-made exhausts.

This behemoth is powered by three bored-out CB750 motors which essentially makes it a 12-cylinder 2,508cc glory, a mean feat that really hasnt been replicated since the days of Russ Collins in the 70’s.

So much hand crafted work you dont even see, his attention to detail is unsurpassed and I can relate to the hard work that has gone into to create such a work of art.

Just to dial all three of these in with 4 Keihin FCR 35mm carbs to each cylinder, must of been a mechanical nightmare to say the least, so Kudos to you Kiyo for patience alone.

A very skilled and self motivated man that I have huge respect for and at some point try and make the trip down to his workshop to tell Kiyo in person about the way I enjoy his builds, I have known Kiyo for many many years and have always held him in high esteem.

Well done my friend and hope to see some great times placed on the dry lake.

 

 

Steve McQueen’s 1969 “Sandcast” CB750 Honda SOHC up for Grabs

This is a rare “Sandcast” 1969 Honda CB750 “Sandcast” that’s historically significant for two reasons, firstly it was the world’s first “superbike” and secondly it was bought new by Steve McQueen through his production company Solar Productions.

For those who may not know about this 500 pounds of Iconic Motorcycling Mastery, here is a small run down of the inline four Japanese History.

Having captured five consecutive championship titles in the historic 1966 World Grand Prix Road Racing Series, Honda decided to withdraw from the World GP circuit beginning the very next season. Upon that announcement, the company turned toward its primary target; the development of high-performance consumer machines. Thus it would achieve through the application of technology obtained in road racing.

Honda was in those days exporting more than half of its Japanese-made motorcycles. The company, however, did not offer large-displacement sports bikes, even though they were in great demand in developed countries such as the U.S. Moreover, sales of Honda motorcycles in America had begun to drop in 1966. Accordingly, American Honda had been asking for the development of new products.

The Dream CB450 was released in 1965 as a high-performance bike. Featuring a two-cylinder DOHC engine, it had been created at the request of American Honda, which wanted a higher-class version of its predecessor, the 305 cc CB77. Yoshiro Harada, who was in charge of the development project, reflected on the product’s history.

“In 1960,” he recalled, “the U.S. market for large motorcycles was approximately 60,000 units annually. Of these, most were imports from British makers. The Japanese market was comparatively much smaller, with monthly sales of several hundred units. But through our understanding of the situation we decided to develop a 450-cc bike, specifically a mass-production model, that could be sold in the U.S. as well as Japan.”

The CB450 sold relatively well, but it did not win acceptance as a major product. The majority of American riders, it seemed, did not judge motorcycles simply by how fast they could go. They also wanted responsive torque performance so that they could get the power they needed without downshifting. For many local riders, motorcycles represented a means of recreation and relaxation rather than rocket-sled performance.

Harada visited the U.S. around the summer of 1967 to observe the CB450’s impact in local markets. He even went so far as to detail the machine’s superior performance to the staff at American Honda, telling them it was even better than the 650 cc models by Norton and Triumph. However, they did not see the point in riding a 450 cc bike. Instead, they simply held to the belief that “bigger was better.”

The 650 cc displacement size was the largest to be found in Japan, yet these bikes accounted for only a few percentage points in the overall market. Harada therefore decided to develop a bigger model, as an obvious nod to the U.S. market. However, the request given by American Honda, ‘”the bigger the better,” seemed quite vague to him. Based on that advice alone, it would be difficult for Harada to determine the right displacement.

It was then that Harada learned from a reliable source that Britain’s Triumph was developing a high-performance model with a 3-cylinder 750 cc engine. This bit of news determined the engine specification. By October 1967, the outline for Honda’s new larger cc model had been defined: it would be driven by a 750 cc engine having a maximum output of 67 horsepower (one more than Harley-Davidson’s 1300 cc unit, whose maximum output was 66 horsepower).

A team of about twenty members was assembled on behalf of the development project in February 1968. The design of the CB750 FOUR had officially begun. However, Honda was already the industry’s leading producer of motorcycles, thanks to the popularity of its classic Super Cub. By introducing the CB750 FOUR, the company planned to become the world’s top manufacturer in terms of quality as well as volume. This model’s competition, however, would be formidable, since the pack included comparable models from Triumph, BMW, and Harley. Therefore, the new Honda would have to offer a superior level of performance and reliability in order to lead the field.

A 4-cylinder, four-muffler engine structure was to be the basis for design so that riders in every market could immediately associate the bike with the stunning performance of Grand Prix machines. Moreover, the handlebar position would be elevated – popular among American riders – to emphasize the bike’s dynamic, “wild” image. As Honda’s first mass-production model with a large powerplant, the CB750 employed various technologies designed to ensure high production volume and easier maintenance for the owner.

Integrating Design with Human Engineering

The objective of Honda’s basic development plan was to make long-range, high-speed touring safer and more comfortable, while achieving superior output. Therefore, the emerging science of human engineering – called “ergonomics” – was to be incorporated structurally, right down to the finest detail.

To facilitate the collaborative process among design engineers and production personnel, common engineering targets were established for product development. These included the following:

[1] Ensure stability during high-speed cruising (between 140 and 160 km/h) on highways, yet retain an ample margin of output for effective maneuvering in traffic.
[2] Provide a braking system that is reliable and resistant to high loads by anticipating frequent rapid decelerations from high speeds.
[3] Minimize vibration and noise in order to reduce rider fatigue during long-range cruising. Provide an ideal riding position for comfort and the proper operation of controls based on human-engineering principles, and design the mechanisms so that the rider can easily learn how to operate them.
[4] Ensure that various ancillary devices, such as lights and instruments, are large and reliable. They must be designed to help the rider make sound judgments and ensure sufficient visibility for surrounding vehicles.
[5] Extend the service life for each device and ensure that it provides for easy maintenance and servicing.
[6] Create original designs that also are easy to mass produce by utilizing newer, better materials and production technologies. This applies particularly to cutting-edge surface-treatment technologies.

The satisfaction of these requirements meant that the team would have to utilize the vast reserves of engineering information Honda had accrued in the manufacture of Grand Prix machines. Moreover, computer systems would be introduced in order to streamline the various steps involved in development. However, computerization ultimately did more than that. It increased the efficiency of numerous development tasks, including plan modification in the prototype phase, design changes, hardware modifications, and testing. It even reduced the time needed to plan a line for mass production of the CB750 FOUR.

The First Motorcycle to Offer Disc Brakes

Fortunately, Harada had come across some after-market disc brakes in a motorcycle accessory outlet during his trip to the U.S., and they had proved effective in the CB450. As a result, he immediately visited Lockhart, the developer and manufacturer. After consulting with the supplier’s staff regarding the ideal design, Harada left the company with a set of their products. He secretly believed the new model they were going to develop might offer an opportunity to adopt disc brakes.

The day of the 1966 Tokyo Motor Show, scheduled for October, was fast approaching. However, Harada was still unable to make up his mind. Therefore, he brought two different brake specifications to Soichiro Honda and asked for some advice.

“We’ve designed two separate specifications having different braking systems,” he told Mr. Honda. “One uses conventional drum brakes and the other had disc brakes. Of the two, the disc-brake specification had only recently been developed, so it will need more tests. If disc brakes are adopted, we aren’t sure we can meet next spring’s completion target.”

Mr. Honda’s reply, though, was simple and direct: “Well, of course we’ll have to go with disc brakes.”

The CB750 FOUR was a hit at the Tokyo Motor Show, flashing its big disc brakes to throngs of admirers. Rave reviews began pouring in.

However, immediately following the show, many hours were spent analyzing the remaining problems. Before the model’s commercial launch issues that needed to be solved included increased wear of pads and noise in the brake pads, problems that were generally associated with disc mechanisms. They had to be solved in order to “achieve higher power while maintaining safety,” which was a key requirement in the development of the CB750 FOUR.

Mr. Honda, in his reply to a question from an engineer, explained Honda’s objectives in developing the CB750 in the January 1969 issue of the company newsletter (No. 124):

“When I went to Switzerland last June,” he said, “a policemen on a white police motorcycle came into the park where we were. He then got off his bike. I was watching it, thinking what a small motorcycle he was riding. I was amazed to find it was a Triumph 750 cc. So, actually the motorcycle was fairly big, but it looked small since the policeman was so big. [Laughs] I knew then that our bikes wouldn’t sell in foreign markets if we kept building them according to our Japanese perceptions. That’s why I suddenly became enthusiastic about this, and it’s why I started telling them to develop a bigger model as soon as possible.”

The CB750 FOUR was released in the U.S. in January 1969. That year, Honda held its first U.S. dealer meeting in Las Vegas, Nevada, a gathering of motorcycle dealers from across North America. The meeting’s objective was to motivate sales, which had been sluggish since 1966. As a strategic move prior to the coming spring season, the meeting was also attended by company representatives from Japan, including Soichiro Honda himself. The event’s true highlight was the introduction of the CB750 FOUR and other new models such as the Z50 and SL350.

“A retail price of $1,495 was announced by American Honda’s President Kihachiro Kawashima at the Vegas meeting,” Harada remembered. “Since large bikes were selling for between $2,800 and $4,000 in the U.S. at that time, all 2,000 dealers burst into thunderous applause when they heard its price. I’ve even heard that the machine fetched a premium as soon as it was on the market, selling for $1,800 to $2,000.”

Honda was soon deluged with orders for the CB750 FOUR, and the initial production forecast of 1,500 units a year became a monthly figure. Even that, however, was not enough, so the number jumped to 3,000 units.

Employing an Idle Facility to Produce a Large Motorcycle

Saitama Factory (currently Wako Plant) and Hamamatsu Factory were in 1969 selected to produce the CB750 FOUR’s engine and body, respectively. American Honda sent two engineers to Saitama Factory to join the staff for a series of tests, in which 300 items were checked from the user’s perspective. Honda Motor had high expectations for the exportation of the CB750 FOUR which was believed to be a strategically important bike for increasing the sales of other Honda models on the U.S. market.

This was Honda’s first attempt to market a big bike, and therefore it would be hard to forecast sales accurately. For that reason each plant decided to make effective use of idle production facilities, normally used for power products. This would serve to minimize the company’s overall investment. Modifications and overhauling, however, would be needed before their equipment could be used to build the CB750.

Honda’s previous models used a spilt-type, press-fit crankshaft having a needle bearing. However, the four-cylinder powerplant in the CB750 FOUR employed an integrated crankshaft and metal bearing. At Saitama Factory, the staff wracked their brains trying to identify the right machining equipment and line configuration to produce a part they had no experience making. They even visited automobile manufacturers in order to acquire some knowledge they could use to plan the line.

Efficiency on the line was poor initially, and as a result the production volume was at most five units per day. However, the machine became an instant smash hit, bringing tears of joy to everyone involved with the CB750’s creation. The initial production forecast of 25 units per day was pushed up to over 100 units. Back orders piled up as a result of this explosive, yet completely unexpected sales activity. Soon, the production of sand-molded crankcases, for which the factory did not have a dedicated machine, could no longer meet the rate required for mass production. In response, the entire crankcase production facility was upgraded to adopt the metal die-cast type. The line was gradually enhanced as production volume increased. However, every time the volume was adjusted, additional employees would be mobilized to run a temporary line. Everything had to be accelerated in order to produce such a number of bikes at Honda’s level of quality. Ultimately, though, the production of engines and bodies was transferred to Suzuka Factory – in July and October 1971, respectively – as part of the company’s endeavor to satisfy customer demand.

Suzuka Factory was then building the CB500, using a production line within its automobile plant. However, there were problems with this facility, including a restrictively narrow corridor along the line that hindered the smooth flow of parts. Therefore, with the assumption of CB750 Four production, the factory took a long-term view and changed the L-shape line for body assembly to a straight-line configuration. The move offered a better work environment and vast improvements in employee safety.

The organizational structure and operator training were improved, too. To that end, a dedicated organization was formed for the production of the CB750 FOUR by gathering selected personnel from the Honda 1300 and TN lines. The resulting vacancies on those lines were then filled by personnel from the factory’s auto plant. Those assigned to the motorcycle production line were then given orientation concerning the major differences from automobile production, particularly with regard to the prevention of damage to the product’s exterior. Accordingly, the line started up on schedule, with all cost and quality objectives satisfied.

Creating the Nanahan Boom

Honda had succeeded again, bringing other Japanese manufacturers into the arena with sports bikes featuring large, 750-cc engines. Therefore, it is no exaggeration to state that the Honda CB750 FOUR was a pioneer model in that regard. In fact, it gave birth to a new category known in Japan as “Nanahan*1.” Yet the Honda model, with its decidedly high-performance intentions, also fared very well on the racing circuit.

The in-house racing team at Honda R&D brought their CB750 Fours to compete in the Suzuka 10-Hour Endurance Race scheduled to be held in August 1969, soon after the model’s commercial launch. Honda dominated the race with a one-two finish by Blue Helmet MSC. The team of Morio Sumiya and Tetsuya Hishiki took first place, while the pairing of Yoichi Oguma and Minoru Sato came in a close second.

Veteran rider Dick Mann, meanwhile, streaked to victory on his CB750 FOUR at the AMA Daytona 200-Mile Race in March 1970. It was a ride that sent customers throughout the States running to their Honda dealers. In reflecting their conviction that “bigger is better,” American riders soon wanted a bigger bike with an engine offering even larger displacement.

The American hunger for large bikes was enhanced with the 1972 launch of Kawasaki’s hot new 900 cc ZI. Forced to develop a more appealing sport bike with a larger engine, Honda launched its 999 cc Gold Wing GL1000 in the American market. The units were initially exported from Japan, but as demand grew production switched to Honda of America Manufacturing (HAM). In May 1980, the first U.S.-made GL1100 machine rolled off the line. It was very well received in the U.S., becoming a major force in the growth of local production activities.

Note:
*1 Nanahan: Meaning 750 in Japanese, the term was used by the development staff to maintain the confidentiality of their new model. Nanahan later became a popular term, and was widely used in magazine circles.

Steve McQueens ” Sandcast” CB750 Sandcast is now up for grabs.
This 1969 Honda CB750 is an early-production model that was acquired by Steve McQueen’s Los Angeles–based Solar Productions movie production company in July 1969. The bike is powered by a 736cc inline-four featuring a “sandcast” case and is finished in red with chrome fenders. Features include a five-speed transmission, a chrome four-into-four exhaust system, quad Keihin carburetors, an electric starter, a front disc brake, street lighting, a two-up seat, and both center and side stands. The bike was acquired by the seller in 2016, reportedly from its second owner of 45 years, and subsequently underwent a two-year mechanical and cosmetic refurbishment that was completed in February 2022. This CB750 K0 Sandcast is now offered with original sales documentation, a letter from Honda Motor Company, a copy of an invoice from American Honda, refurbishment records, a Honda tool kit, a yellow-on-black California license plate, and a clean California title in the seller’s name.

The fuel tank was refinished in Candy Ruby Red with gold and black stripes, and the oil tank, side cover, upper fork covers, and headlight bucket were painted to match. The duplex-cradle frame was media-blasted and repainted black. Features include chrome fenders, street lighting and reflectors, a two-up seat with chrome trim and a rear lip, folding passenger foot pegs, and both center and side stands.

Re-chromed rims measuring 19″ up front and 18″ at the rear are laced to clear-coated hubs with zinc-plated spokes and were mounted with IRC Grand High Speed GS-11 tires during the refurbishment. Suspension consists of a rebuilt telescopic fork with black rubber gaiters and clear-coated sliders as well as a swingarm mounted with dual chrome-shrouded shocks. Braking is from a disc with a rebuilt caliper up front and a drum at the rear.

A re-chromed handlebar equipped with dual mirrors is clamped ahead of instrumentation consisting of a 150-mph Nippon Denso speedometer and a matching tachometer with an 8,500-rpm redline, both of which were refurbished at Motorcycle Gauge Restoration Services in the Netherlands. The five-digit odometer shows 22k miles. Total mileage is unknown.

The 736cc SOHC inline-four features an early-production “sandcast” case with a rough texture formed by a gravity-casting method rather than die-casting that was used for most of the model run. The engine breathes through a quartet of 28mm Keihin carburetors and a chrome four-into-four exhaust system. An overhaul of the engine at Charlie’s Place of Glendale, California, in 2019 included replacement of the timing chain, tensioner, roller, and guides as well as the pistons, stator, starter, and points covers.

 

Engine number 1001370 falls within the range of the approximately 7k Sandcast engines produced.

Power is sent to the rear wheel through a five-speed transmission and a replacement drive chain.

A copy of a July 1969 invoice from American Honda to the dealership owned by McQueen friend, stunt double, and riding companion Bud Ekins lists delivery of a red CB750 that was noted to be “For Mr. Steve McQueen.” The serial number shown (1001064) matches the number stamped on the bike’s frame, a photo of which can be viewed in the gallery. 

The bike is accompanied by a notice of transfer mailed to the Department of Motor Vehicles in Sacramento, California, from American Honda stating that transfer of ownership to Solar Productions Inc. was made on July 23, 1969. The card lists a vehicle identification number that matches the number stamped on the bike’s frame and a vehicle license number that matches the yellow-on-black California license plate .

An awesome machine with some great History too.

The Dispatch Cafe Machine 1975 CB750 F Super Sport S.O.H.C.

Been a while since I have tinkered in the Barn, I am starting to do a bit of creating on a machine I have had as a stock bike and sat in storage for many moons, and I thought to myself, why not create something that I personally rode back in the day and in the style of what was the latest Motorcycle hitting the TON back in London.

I have loved bikes as a kid and my bedroom was literally covered from walls to ceiling in motorcycle posters, of course I loved the Cafe Racer scene and had many Dunstall style bikes on my wall, but wanted to have something similar when I was old enough to ride.  I actually put Clubman bars on my first ever little moped as a crazy 16 year old, I had a Bikini Fairing on the front and a little expansion on that ride, I loved it.

I was a Dispatch rider in London and Birmingham, delivering stuff all over the UK but many trips around the City of London to iconic places like Buckingham Palace , The House of Lords, Newspaper and Magazine Companies, to dodgy Porn Video tape sellers in SOHO, but I loved it.  In London especially, you needed to be able to carry as much as you could for the better wage, but you also needed to be a streamlines as possible to speed through the busy roads of London.

The Creation I am putting together reflect my life, so not a quick build, this is something I will take my time on and weather you like it or not, it will be something that is really a part of me and my life on two wheels. It will take some sorting out to fit the Original Avon fairing that was indeed on a Dispatch bike in London, I have had it years its beaten up and half missing but that’s perfect as we never had any money for lavish New parts, we bought stuff out of a paper called the “Exchange & Mart” then fitted it and never really had time or cash to fully paint it, so this will be great for the ride and I hope I can fit this to the machine to work just like it did when I was a lot younger. LOL!

 

I used to spend many an hour looking through that rag as it was only 15p and I am sure people back home in Blighty reading this will also remember doing the same, no internet then ha ha.

I am happy that I can do this and reflect on the years that have seemed to have flown by, no idea where the 140 pound Skinny Fella went to but I can always reminisce with this build, the bike was super heavy but strong as an Ox, I hope to get the bike completed sometime this year and will show it as a feature on the website.

I may go with a different seat of mine, I have already tried 5 different seats and still not happy, but thats half the fun of designing something and when I get it right, I shall feel a whole lot happier.

You used to see so many of this style when I was riding around Oxford or regent Street, on a busy Tuesday morning, having a fairing and side Panniers gave me so much more loading space, some days I would even fit a back rack and a top box, but that did get a little over laden at times.

I think I have a screen for it but can get one from a company here or in the UK, so no worries on that, but a long way to go as I have to allow for the steering to move smoothly and not catch anything mid turn.

Of course I shall have a headlight in the fairing, an old style one too and the obligatory Fog lights as well, fun times ahead and thought that i would share.

 

 

 

 

FOR SALE : 1977 CB550F SOLD – SOLD -SOLD -SOLD- SOLD

Geoffrey Chaucer once said ” Time and Tide wait for no man.”  And to be honest, he is right, I have many pokers in many fires and as we moved to a bigger place with my very own workshop, I thought some of my stuff in storage can go to others, as I have a lot of things to build, finish and design.

So here it is:

A 1977 CB550F Super Sport HONDA FOUR Project of which I have had for quite some time in my storage container.

This bike is rolling and I also have the Pink Slip and the numbers all match up too.

Still needs finishing but all the hard work is done to be honest and would make a fun Bar hopper or parts runner when completed.

 

 

The Motor was rebuilt, needs a sprocket cover as we cant seem to find the old one, but there are many things on here.

Here is a list or two,

This will make a great project for someone and is priced really well to sell, I also look forward to seeing it completed and on the road sometime very soon too.

It sits so very well and that’s how I envisioned this build when I started to acquire parts for the inline four Honda.

I have always liked the Old School Diamond treaded tires, they are not cheap as well and this makes such a good deal for a client out there as there are many cool parts on this ride as you can see by the photos I just took today.

This Motor has a Stainless Steel 304 grade Four Into 1 set up and that this style is a frame hugging design that I think will turn heads when it fires up.

Just look at them Chunky tires, this really is a great looking ride and it will travel along the gravel very smoothly indeed.

It has a set of Piggy Back shocks on the rear to set the Arse just right for them tall tires.

Still needs things like a drive chain and a front sprocket but this is all easy stuff to be honest.

These little 550 bikes are a great powerhouse and will surprise many people when you get this on the tarmac.

Has a 5-3/4 steel headlight with an LED set up that is brighter than Einstein.

I put on expensive handlebars and these really do feel super comfortable and no wrist ache what so ever, also fitted early 1970’s Race throttle and grips for an added bit of Nostalgia.

So here she is, like I said, I have the PINK SLIP-TITLE for this and the Numbers match, so a cool deal for someone out there.

Thanks for looking and Maybe you can pass this along to some of your friends, you will notice the Original speed equipped finned Points cover too?

 

 

 

The KC Special CB750 Honda inline Four

I have always loved creating My style of machine for Customers and this one is no exception, the KC Special turned out to be a great looking ride and the Owner Keith Conrad ( Hence K.C.) lives in Milwaukee and asked if I could revamp his old 1975 CB750 into a Silver and Black Cafe bike, I said sure thing and the deal was done, a build sheet was agreed upon and Keith sent the bike out to me.

I took the bike apart, right down to the frame, as I do all my builds, then I set about cleaning the frame up some what and smoothing some of the old factory welds, as Honda welds are quite rough back then as i guess they were hand welded and not automated as they are today.

As you can see, I took my time as I wanted the frame to really look nice in a Gloss Black on this build, I wanted it better than factory, so I took a long time to make sure that this Chassis came out nice, as i mostly powder coat my frames, unless I am using Candy Paint or Metalflake etc. Above you can see how Glossy the main frame rails are.

I took the stock gas tank and using my Egg Hammer, I pounded the sides to create Knee inserts, so you can tuck your legs in tighter to the bike and get a little more stream lined, just as they did back in the day for racing etc, this is no easy task and you will see how much it takes to do when you have a go your self, but worth the look in the end thats for certain.

The Paint scheme is High Gloss Black with Metalflake Silver panels and racing stripes and I really needed to make sure that this flowed well, and am happy with the result.

Plenty of Detail too, I hand machined out of 6061, a Custom Finned Oil Tank Dip Stick cap, this really did look trick, compared to the stock version.

Its like the saying says, the devil is in the detail and there is plenty to look at on this CB750 Cafe Bike and am stoked how the bike turned out in the end, worth all the hard graft.

The seat is one of my own that I manufacture, called “The Rocket 4” its a sleek sturdy and well rounded seat base that I produce and has the same curve as the gas tank, that way the body work then flows and give the machine the Status Quo.

Keeping in the theme of Old School styling, the seat upholstery was hand machined and small 1 inch Diamonds in white stitching with Silver piping and vintage snaps was completed to really make this stand out from the crowd.

I used an LED Custom Tail light that I offer on my website and this is bright as Einstein, and I think is a nice addition to the back of the Rocket Four seat unit, also the silver flake racing stripes really stand out nicely.

I machined some covers for the rear piggy back shocks as well as making some risers for the lower, to increase the ride height by 2 inches, out of 7071 Military spec Aluminum.

I also Chromed the rear swing-arm and hand made then Chromed a Custom Chain Guard to show the Gold 530 X-Ring chain off, I also polished the Hubs of the rims and painted the centers black to give a nice offset.

The Motor was rebuilt, as well as the carbs and synchronized etc, my Custom Oil lines were added in Black for a nice offset too, I fitted an oil Pressure gauge to keep the rider informed as to what is going on below.

As you can see, there is plenty going on here, I took a lot of time on the front sprocket cover and I even polished the rear set brackets for a more Custom look too.

Rebuilt and polished Carbs with hand machines velocity stacks from Steel Dragon really help the look of this bike and give it that Nostalgia look and it runs really hard too, there is something about hitting 6 grand on a 750, then you know you are starting to pull like a steam train.

People ask me about my gauges that I create on these inline four machines, and this one is no exception, unless I am restoring a bike, I don’t really care for the Honda’s Gauge faces as they are Green or Blue, not my favorite color of choice to be honest, wished they would of gone Black with White numerals like the Classic British machines, but oh well, so what I do is take the gauges apart and then I fit my Custom faces thats an overlay I print out, then repaint the needle and add chrome cups to embellish the bodys and give it a little more Custom look.

I have always liked to do this and it really does personalize your gauges, this time I went with the Cafe Racer Font and crossed Flags of which I think suit this Motorcycle to a Tee.

You may also notice that I have fitted a 2 inch handle Bar riser, to give a more comfortable riding position and easier strain on the wrists too, then fitted my Relocation bracket on top of the handle bar clamps to clean the top end of the bike up, with a BIG oil pressure Display light to match the Needle ends.

This is one tasty ride, the 4 into one system of mine is Ceramic Coated Silver, its a great look, almost a brushed polished Aluminum look to it, and she barks like a scolded dog when you get on the loud button, you will also noticed I machines a Finned Stabilizer Bar at the rear of the bike and did my usual drilling on the brake hub to let brake dust and heat escape under hard braking.

A lot of time and energy went into creating this machine and the owner really digs it, it is just how he wanted it and am glad that i was able to oblige with his demands.

The Customer wanted Gloss Black Rims with stainless spokes and he really did like the way these turned out on the bike and the attention to detail that I am known for on these inline fours.

I always fit an Oil pressure Gauge, as I do not trust the Honda Pressure switch thats behind the Barrels, so these run great and give true pressure as soon as you fir the bike up, as it is connected to the oil galley plug.

As you can see, New Levers, new Control switches, new Handle Bars, polished triple tree, New cables, New master cylinder and stainless nuts and bolts through out this motorcycle.

A great but solid Motorcycle, with aggression when you want it, reliability for everyday riding, and an awesome stance to give it that moving look standing still, sure does sit well in my stable.

I really did enjoy putting this bike together and felt good to know that I had done all and more than the Customer had asked me about, its one fine steed and I enjoyed slinging my leg over it.

I wanted to share it with you guys and Gals and hope you like what I have created too?

Maybe if you are in Milwaukee area, you might come across the KC Special? if you do, take a snap and send it to me, love to see it again.

 

Another Year awaits, Have Fun Building your Machine

Well, what a bloody tough year we have all had, for me it has been crazy, what with moving to another location as well as catching Covid and then on Christmas day catching an awful cold with the same symptoms of Covid but without the temperatures, its been a long battle throughout.  From having some of my suppliers completely closing down due to the Virus to some retiring early, I have had to come up with some more ideas for parts and apparel to have for the coming year we await.

But, the positive side to this awful dilemma we are all facing right now is, we have some time in our garages. sheds or back yards, to turn a wrench, help a mate or give a whole new project a go and take any frustrations out of what’s going on in the world and turn it into a working machine that is yours and yours alone.

I love making parts or building new rides, its a therapy and an escape from life’s woes to be honest, and also there are many many failure before I find something that fits and works as it should, so for those who are trying it on your own, or building your own machine, Failure is a learning curve, we all do it and not only once. I have almost given up on a particular piece I was trying to make, I left if for a day or two and when I head a fresh brain, it all clicked and worked.

Do not be afraid to fail, I have sat and pondered and even been seen to shout at the parts calling it all sorts of names but in the end we managed to come up with a result that we are happy with, the fun is in the creating at most of course, taking your ride out and stretching its legs for the first time is such a thrill and the Euphoria is un measurable, but what I am trying to say is

Dont Give up”  There are many friends on the internet that can I advise, heck, I even put my phone and text number on my website so people can text me, rather than waiting all weekend for an answer from a company phone, i want to help the best way I can, its not all about sales for me, its Service and the camaraderie of the fellow builder.

I am hoping that this coming 2021, we can all have fun in what we do and maybe even meet at an event or on the tarmac, or at the very least, on the end of the phone of email, there is something self gratifying when you complete something on your own machine and I receive many emails and photos from customers who have really enjoyed creating a unique Motorcycle that they want to personalize for themselves.

Hoping that you can get some time and turn a wrench and have fun with that two wheeled machine of yours and maybe I can help with parts or advice?

Wishing you ALL a very Happy New year that’s almost upon us and thank you from the bottom of my heart for all your orders from around the globe, you all Rock!!!!

 

Here is a little video I saw on you tube of a guy with minimal tools rebuilding his little Honda Cub.
