The Chang Jiang 750 is a Chinese sidecar motorcycle whose design traces back to the Soviet M-72, itself based on the BMW R71 of the late 1930s. It uses an air-cooled 745cc side-valve flat twin and shaft drive.
It was built for the Chinese military and later sold to enthusiasts abroad. It is simple and rugged, and has a following among classic sidecar fans. Relatives include the Ural and Dnepr.
