The BMW R75 is a World Battle II-era motorcycle and sidecar combination produced by the German company BMW.

In the 1930s BMW were creating a number of popular and impressive motorcycles. In 1938 development of the R75 started in response to a get from the German Army.

Preproduction types of the R75 were power by way of a 750 cc area valve engine, which was predicated on the R71 engine. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine motor for the R75 device. This OHV engine 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 linked to the trunk wheel of the motorcycle. They were fixed with a locking differential and selectable road and off-road gear ratios through which all four and reverse gears did the trick. 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 generally employed by the Wehrmacht in Russia and North Africa, though after a period 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 making a Z?ndapp-BMW hybrid (chosen 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 models, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 each year.

Since the aim for of 20,200 BMW R75's had not been reached, it remained in production before Eisenach manufacturing plant was so badly harmed by Allied bombing that development ceased in 1944. A further 98 units were constructed by the Soviets in 1946 as reparations.
