The BMW R75 is a World Battle II-era motorcycle and sidecar mixture produced by the German company BMW.
Inside the 1930s BMW were creating a range of popular and highly effective motorcycles. In 1938 development of the R75 started in reaction to a get from the German Military.
Preproduction types of the R75 were powered with a 750 cc part valve engine, that was based on the R71 engine unit. However it was quickly found essential to design an all-new OHV 750 cc engine for the R75 device. This OHV engine motor later became the foundation for following post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was driven with an axle connected to the rear wheel of the motorcycle. We were holding fitted with a locking differential and selectable road and off-road equipment ratios by which all and invert gears worked. 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 broadly used by the Wehrmacht in Russia and North Africa, though over time of evaluation 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 building 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 arranged that the manufacture of the R75 would stop once production come to 20,200 products, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.
Since the concentrate on of 20,200 BMW R75's had not been reached, it remained in production before Eisenach factory was so badly harmed by Allied bombing that development ceased in 1944. An additional 98 products were assembled by the Soviets in 1946 as reparations.
