Note: The earliest Chang Jiang 750 M1 model was a 6V system with a kick start
only. The battery was used only when the electricity needed and the engine could not produced
it. Anything else was almost the same as CJ 750 M1M. The main difference between the CJ 750 M1M and CJ 750 M1Super model are
the engines: SV 24 horsepower vs. OHV 32 horsepower. Max. speed depends on how you
want to customize the 4th gear and final drive, please keep in mind that this
bike is
a 1938's designed motorcycle, please do not overdo on that. No additional modifications
are needed
to drive our Chang Jiang 750 vintage sidecar motorcycles on a modern
highway because it is a way ahead of its time design. Please email me with any
