The BMW R75 is a global Battle II-era motorcycle and sidecar combination made by the German company BMW.
Within the 1930s BMW were producing a variety of popular and impressive motorcycles. In 1938 development of the R75 started in reaction to a request from the German Army.
Preproduction models of the R75 were powered with a 750 cc area valve engine, that was based on the R71 engine. However it was quickly found essential to design an all-new OHV 750 cc engine for the R75 device. This OHV engine later became the foundation for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was driven with an axle linked to the rear wheel of the motorcycle. They were installed with a locking differential and selectable street and off-road products ratios through which all and invert gears did the trick. This made the R75 highly manoeuvrable and capable of negotiating most surfaces. Additional motorcycle manufactures, like FN and Norton, provided an optional drive to sidecars.
The BMW R75 and its own rival the Z?ndapp KS 750 were both generally employed 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 after standardization of parts for both machines, with a view of eventually developing a Z?ndapp-BMW hybrid (specified the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. In addition they arranged that the production of the R75 would cease once production come to 20,200 models, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 each year.
Since the focus on of 20,200 BMW R75's had not been reached, it remained in production before Eisenach factory was so terribly ruined by Allied bombing that creation ceased in 1944. An additional 98 units were put together by the Soviets in 1946 as reparations.
