The BMW R75 is a World Conflict II-era motorcycle and sidecar combination produced by the German company BMW.
Inside the 1930s BMW were producing a variety of popular and highly effective motorcycles. In 1938 development of the R75 started in response to a need from the German Army.
Preproduction models of the R75 were run by a 750 cc part valve engine, which was predicated on the R71 engine motor. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine unit for the R75 unit. This OHV engine motor later proved to be the basis for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was motivated with an axle linked to the rear wheel of the motorcycle. We were holding fixed with a locking differential and selectable road and off-road gear ratios through which all and invert gears functioned. This made the R75 highly manoeuvrable and capable of negotiating most areas. Additional motorcycle manufactures, like FN and Norton, provided an optional drive to sidecars.
The BMW R75 and its rival the Z?ndapp KS 750 were both generally used by the Wehrmacht in Russia and North Africa, though over time of analysis it became clear that the Z?ndapp was the superior machine. In August 1942 Z?ndapp and BMW, on the urging of the Army, agreed upon standardization of parts for both machines, with a view of eventually creating a Z?ndapp-BMW hybrid (designated the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also decided that the manufacture of the R75 would cease once production come to 20,200 devices, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 every year.
Since the goal of 20,200 BMW R75's was not reached, it remained in production until the Eisenach factory was so badly ruined by Allied bombing that development ceased in 1944. An additional 98 devices were constructed by the Soviets in 1946 as reparations.
