The Chang Jiang CJ750 (Simplified Chinese: 长江 or traditional Chinese: 長江) is a Chinese motorcycle, that was manufactured by the China Nanchang Aircraft Manufacturing Company. The same company that manufactured the Nanchang CJ-6 airplane.
The CJ750 was originally produced for the Chinese military and was powered by a four-stroke 746cc engine, with a rear-wheel shaft drive train. The engine is air-cooled, and nearly all the original CJ750s had a sidecar.
Early in the Cold War, the People Liberation Army reverse-engineered the German Zündapp KS 500 motorcycle. Starting in 1951 the Chinese government built 4,248 Zündapp replicas before the Soviets considered the M72 (the soviet version) obsolete. Soon after the Chinese acquired the tooling to build their own M72s named the Chang Jiang 750.
