The BMW R75 is a World Conflict II-era motorcycle and sidecar blend produced by the German company BMW.
Within the 1930s BMW were producing a quantity of popular and highly effective motorcycles. In 1938 development of the R75 were only available in response to a get from the German Army.
Preproduction types of the R75 were powered by a 750 cc aspect valve engine, which was based on the R71 engine motor. However it was quickly found essential to design an all-new OHV 750 cc engine unit for the R75 product. This OHV engine motor later became the basis for following post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was influenced with an axle linked to the rear wheel of the motorcycle. They were fixed with a locking differential and selectable street and off-road products ratios by which all and reverse gears performed. 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 own competitor the Z?ndapp KS 750 were both greatly used by the Wehrmacht in Russia and North Africa, though after a period 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 Military, agreed after standardization of parts for both machines, with a view of eventually creating a Z?ndapp-BMW hybrid (designated the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also agreed that the produce of the R75 would cease once production come to 20,200 items, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 every year.
Since the goal of 20,200 BMW R75's was not reached, it continued to be in production until the Eisenach manufacturing plant was so badly ruined by Allied bombing that creation ceased in 1944. An additional 98 units were set up by the Soviets in 1946 as reparations.
