The project's commencement centers on the crankshaft, with Michal and Eugene also contributing. Comparable to the Iz 350 project, this venture is anticipated to be successful. In August 1939, a Non-Aggression Treaty was signed between Germany and the Soviet Union in Moscow. The R71, considered a civilian motorcycle and rendered almost obsolete due to the development of R75, might have been part of this plan. Between 1939 and 1945, approximately 13,349 machines were produced by IMZ (1939: 1753; 1942-45: 7773) and GMZ (5576). Remarkably, the IMZ Ural factory claims to have stolen the design. Soviet engineers in Moscow covertly purchased five motorcycles from Sweden and reverse engineered every detail, creating molds and dies for their own engines and gearboxes. In early 1941, M-72 trial samples were presented to Stalin, who approved immediate production.
