Honda CB350 CB400 CB500 CB550 CB750 Fours Parts

Honda CB350-750 SOHC Fours

1969 was a pivotal year in motorcycling.  Honda launched their landmark CB750.  For the first time you didn't need to be a mechanic to own a motorcycle.  Smooth, reliable, AND it didn't leak all over your driveway.... yes!

The inline 4-cylinder engine was a marvel.  Chain operated overhead cam, 4 individual exhausts and a disk brake up front.  Honda drew riders to the machine like bees to honey.  Not only incredibly popular on the street, the CB750 appeared on race tracks as the CR750, and in the drag racing world, Russ Collins shoe-horned two of those engines into a single frame - and soon replaced that with his infamous 3,300cc 12-cylinder triple engined monster of a drag bike - the "Atchison, Topeka & Santa Fe".  

As the 1970's progressed, Honda improved and restyled the CB750 with a slightly higher performance engine and a 4-1 pipe to create the Supersport version.  Honda broke additional new ground with an automatic version of this masterpiece.....  

In the 70's choppers and cafe racers weere often based on the CB750, so it is not unusual to find some heavily modified versions out on the road today.
