The M-72 was a motorcycle built by the Soviet Union. Conceived as a replacement for the two heavy motorcycles used by the Red Army, the TIZ-AM-600 and PMZ- A-750, both of which had performed unsatisfactorily during the Winter War against Finland and were considered outdated designs. The replacement chosen was the BMW R71, which had been rejected by the German Wehrmacht as a replacement for the R12. As a result of the Molotov-Ribbentrop Pact, the necessary legal, political and economic procedures were in place for BMW to provide the design, tooling and training for the manufacture of the motorcycle and military sidecar.
