Late Prototype model, the famous pictures Bob Hansen (Summer 1968) received from Honda headquarters in Japan of a completed 750 bike, tank painted in silver with red stripes with very different crankcase castings, drum front brake, K1 type carburetor setup, much flatter "ducktail" type seat, very different exhaust pipes (4) and heat shields. (Both Early & Late Prototypes have an alternator cover that looks unlike anything used on ANY of the following 750's)
