CB350 Board Tracker “Iowa’s Smith Bros”

Sometimes when an artists hits that “BLANK” wall in designing something head turning, it can be way simpler to go “Back To Basics” and there it is, a work of pure art and creativity.

And this is the case with a Motorcycle shop in Cedar Rapids , Iowa. Trying to think outside of the box sometimes is a way lot less stressful than you may ponder upon and Chris Kent and his Team of specialists at the shop thought to themselves that as they were not that far away from the National Motorcycle Museum and as they have visited numerous times, they always seem to be drawn to the area of the classic “Board Tracker”. Simple in athstetics but complicated enough to make many builders turn away from that thought and into something a little more conventional.

The More that Chris thought about this build project, the more idea’s kept exploding in his brain and after a lot of looking at machines, the idea of using a smaller Motorcycle as a platform creation made sense, less clutter, less weight, less on the wallet to an extent as Japanese classic machines running or not are now demanding a premium chunk of change. Also the bigger machines would probably look out of place in a Board tracker the lines would maybe look to bulky and muscular in proportion to a smaller refined machines of the 1970’s.

Now, there is no machine you can just purchase and with small alterations, create a Board tracker, well not one that would be pleasing to the eye anyway, so after much thought and of course searching, Chris came up with a plan of using a 1973 CB30F Honda that they had squirreled away in the shed.  This was the way to go and, with the help of some of the best skilled professionals in the industry, they went about their way in putting together what I think is one of the most iconic Board trackers of all time with a Metric heart and screams a Nostalgic message of Yesteryear.

Now, the CB350f is a great machine in its own right, but with a 53 inch wheel base and Telescopic front forks, the geometry was all wrong for the look of the build that they needed, but, the 350 Engine is a bulletproof little inline four that boasts a 34 Hp @ 10,000 rpm and the motor in stock configuration actually was an impressive 98 mph which is not bad for a 21.s cu in power plant.

Between them, they removed the 350 Honda from out of the shed and man handled the 373 Pound Classic machine onto the Build table to take a tape measure out and see what they had to work with on this 50 year old Japanese 4 Banger. “Initially I was going to try and modify the original frame but once we had the bike stripped down it was obvious that was not a frame that would stand any chance of meeting the design without serious fabrication and at the point, you just as well start from scratch,”

After a discussion and many phone calls, Chris located a frame designer and builder and approached him about creating a new frame to his requirements, as custom hardtail chassis builders are so busy this time of year and not wanting to have a year long fab on just the frame was not in the cards, but it would still take time as Geometry is everything if you want it right, especially  with a beautifully curved single down tube for a tight steering angle.

Now, bringing this frame up to a rolling platform is another thing, Chris and the team thought long and hard on what application to graft to this Board Tracker Custom frame and came to the conclusion that a ’52 big twin springer front end with 19′ Excel wheels laced to the original hubs and Firestone Champion Deluxe tires would be the order of the day and boy did they ring a bell with that set up. But the Firestone tires did not have raised white letters like the trackers of old, so out with the old Rubber tire paint and Chris turned his skills into almost a sign writer and knocked out the lettering in no time at all and these really do stand out amongst the crowd of Blackwall tired machines that you come across. Just that “Attention to detail” That Smith Brothers are known for.

The handlebars were always going to have to be modified versions of another style and they started as 1” beach bars. But it’s the solid milled and knurled brass grips that hide beneath them a super trick element of the build and its tricks like that which really make you stop and look at the amount of time and energy that has been out into this machine that really does make you appreciate what has gone into such a unique build.

Wanting to keep things clean and have no levers at all the first step was to create an internal throttle, with the grips drilled and threaded to suit. Mitchell at Exile cycles had done this to many of his Harley builds and this was a great way of hiding any cables etc, as the tracker bars have a wide curve sweep and really is a good focal point of the motorcycle as there are so many great engineered pieces on this creation, it will take you some time to even notice the work that was done to make this happen. So an internal throttle and clutch set up was fabricated and this functions very smoothly indeed.

From that, the next step was that awkward fabrication of the bodywork that needed to be created, it may be minimalistic but it has to be right on the money to make it look like it should be there. Joe Cooper of Coopersmithing Co. was contacted as he is a wizard at fabricating fenders. With Chris explaining his desire to incorporate a 1.5” wide strip of rosewood down the centre, Joe knew the solution lay in a double rolled bead. But bending the tight fibres of the wood proved more challenging, 5 days in the bath and it still wouldn’t budge.  Luckily a regular around the shop is a woodworker who steam moulded it and added the brass rivets before he turned his attention to the stunning battery/electronics box of the same rosewood.

Now it was time for the tank, “I spent no less than 25 hours mocking up different iterations and sketching out designs that ultimately paid off in the end thanks to our local metal magician Mike Frieden,” Chris says. Not wanting to go over the top with the paint, a single colour, antique white, was chosen. With pin striping star Hugh Hoffman taking care of the gorgeous detail work that has a true traditional feel. You just have to look at this machine and it screams Yesteryear, such classic curves that represent the Board track days and I really believe that even the purists would actually stop and take in the amount of work it took to create such a masterpiece.

There is over 25 hours just in the sketching and mock up drawings of the Petrol Holding receptacle, and gave the plans to Mike Frieden a Wizard of a fabricator to actually turn this design into a functioning piece. The Single Color “Antique” White was chosen for simplicity and gives that age of speed era and a great color choice I think.

The Engine in itself ran fine, as many inline four motors do as they are over built from the factory to be honest, but the carbs didn’t have a lot of spice left in them so a set of Keihin CR’s were chosen to replace the tired out stock versions. Also a reliable spark unit was required to feed enough power to ignite the gas from them race carbs, so a Dynatek Electronic unit was chosen and fitted. The stock headers were slash cut into a zoomie style and then wrapped with heat wrapping and this gives the machine an aggressive growl as you wind the throttle.

 

The wiring was also needed to be replaced and none better than an M unit from Motogadget made sure everything was minimalistically covered and of course reliability is warranted if you want people to see and hear a hand built machine and kudos to the lads from Smith Brothers for turning out a classic looking Board Tracker that’s a great piece of art and a functioning Motorcycle.

Who thought that a little Honda could turn out into such an Iconic Board Track machine and look forward to seeing it with my own eyes soon.

 

 

 

 

 

 

 

 

 

DOWNSHIFT STUDIO HONDA CX500

Well today’s blog is cool as I consider this builder as a friend of mine, DownShift Studio is run by Jeremy Lacy, an industrial designer based in Denver who specializes in illustrations and sketches of custom bikes, often helping fabricators and builders from around the world visualize their ideas and projects before the metal is cut and the tools come out.

Jeremy had done some prototype sketches for me before and even did the memorial Bike Sketch I am creating in memory of my Mum that passed away and will be raffling the bike off and donating to the Hospice when completed.

The Honda CX500 you see here is his first hands-on project, it’s the result of a collaboration between Jeremy and Joel Fitzgerald, and the bike shows far more technical skill than we’re used to seeing in a first custom. I knew that Jeremy would do well as he has the foresight in his sketches to see how something will look when it goes under the knife, and under the knife this old CX500 Maggot went, Jeremy had been learning how to weld and fabricate recently, and this would be an exceptional Sketch pad for his platform bike to transform Honda’s number 1 chosen Dispatch Rider bike, into a head turning Brat/Tracker.

Jeremy’s JD2 Tube bender got a pretty good thrashing, as he designed and hand fabricated the rear tubular swing arm for this CX500 and in its construction Jeremy wanted to make sure that the swing arm had its strong Rigidity and didn’t want any compromise on safety that would cause any sort of issue or integrity of the geometry, with the addition of three safety reinforced mounts to the swing arm, gave this set up a very robust structure to handle any road condition that was thrown at it. Have a look and see the work involved, as this is a great looking machine and now a Mono shock, getting the Geomatary is key here and you will soon see if you got it wrong as the bike will bounce like a kangaroo if the angle of the shock is off.

The Sub frame was hand made using 065 wall Cold rolled steel and shaped at the shop to have that sleek look and a minamalistic feature, then they hand pounded, bent and curved a steel sheet to fit over that frame and sent it off to Master Upholsterer Ian Halcott who did his magic using Low profile high density Foam, then lavished with leather Hyde and stitched to perfection.

The front end of the CX sat too high, giving this Project an ugly stance, so a quick strip down and New Race-Tech Springs were added and then the fork tubes were slide through the upper trees to give that lowered stance that they were seeking. Then the front wheel was painted black to stealth up the 19 inch front and the rear had a new 18 inch Comstar rim also painted Black and then had some Blackwall Shinko 705 Rubber shoehorned on, giving the Honda a better profile and ride now, nice stance and a more comfortable posture for the rider now.

The Bent Four Mill was in pretty good shape, so to save time and money, they just serviced the old girl, removed the stock Carbs and fitted new intake Manifolds of which then got a Brand spanking new set of 34mm Mikunis Gas drinkers attached to make sure this Japanese Iconic  4 Valves per cylinder gets enough Motion Lotion, these are a fun bike, not an arm ripper but the  497-674cc water cooled Longitudinal OHV  80 degree V- Twin gives smooth transitional linear power that just goes on and on and on, how do I know?  I have owned many of them in the UK as I was a Dispatch rider and just having a smooth running motor that handles traffic and of course has great engine breaking, this was a Work Horse machine that I did Hundreds of thousands of miles on over the years.

Plenty of Modern technology sprinkled onto this machine and Jeremy used Motgadget for the two button controls, then they were mounted on a brand new set of Renthal handlebars, the rear of the bike got new LED combination brake light and turn signals to make sure traffic behind him knew he was there. The handlebars received Bran new comfortable grips, New levers and a new throttle assembly set up for a smooth action. The Motor got some detailing too, and the headers were wrapped with some Titanium heat wrap by DEI, on the ends of the headers were fitted some Cone Engineering megaphones that give this V-Twin some Growl.

Jeremy managed to bag, Fettle, smooth and clean up the machine just in time for the  2017 Handbuilt Motorcycle Show of which is one of the best shows in the USA for Hand Fabricated machines that are unique to everyone, this is over in Texas but well worth the trip to show their hard-work off. The Gas tank looks great as all the paint was removed and a Classic brushed finish was completed in time for the show.

Both these guys did a great job and the HONDA CX500 was well received at the show, put on by the super talented  Revival Cycles. Lots of cool work, hiddent electrical harness and of course battery just add to the many hours of time that was eaten up bringing this machine to life, Great Job Guys.
