A similar model is the Soviet (now Ukrainian) Dnepr motorcycle. Both Ural and Dnepr motorcycles are sometimes known by the generic name, "Cossack motorcycles". In fact, between 1973 and 1979, Ural was one of the makes marketed by SATRA in the United Kingdom as Cossack motorcycles. Chang Jiang, a Chinese motorcycle manufacturer, bought the IMZ M-72 production line to build its CJ-750 (original designation Model 1957, M1).

In 1940, the Soviet Union acquired the design and production techniques for BMW R 71 motorcycles and sidecars. The first M-72 model was finished in 1941.
