IMZ-Ural is a Russian maker of heavy sidecar motorcycles. Recently the company has developed a solo motorcycle with no sidecar.
In 1940, the Soviet Union acquired the design and production techniques for BMW R71 motorcycles and sidecars. The first M-72 model was finished in 1941. Originally, factories were to be located in Moscow, Leningrad (now Saint Petersburg), and Kharkov, but due to the approach of Nazi German troops, the Moscow facilities were moved to Irbit, and the Leningrad and Kharkov facilities to Gorkiy (now called Nizhny Novgorod).
A similar model is the Soviet (now Ukrainian) Dnepr motorcycle. Both Ural and Dnepr motorcycles are sometimes known by the generic name, " Cossack motorcycles," which was used between 1973 and 1979 by SATRA in the United Kingdom.
Plans for the M-72 were later sold to the Nanchang Aircraft Manufacturing Corporation, a Chinese industrial firm, to build the Chang Jiang.
