Identifying CB750 Frame Year & Engine Number

Many people ask me about how to tell what year their frame is or what year their motor is, so I thought I would add an identification listing of all CB750 S.O.H.C. models.

With Model, Frame and engine year.

Hope this helps you… as it sure does help me out at times.
