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

In the 1930s BMW were creating a range of popular and impressive motorcycles. In 1938 development of the R75 were only available in reaction to a get from the German Military.

Preproduction models of the R75 were driven by a 750 cc part valve engine, that was based on the R71 engine motor. However it was quickly found necessary to design an all-new OHV 750 cc engine unit for the R75 unit. This OHV engine motor later became the basis for subsequent post-war twin BMW engines like the R51/3, R67 and R68.

The third side-car wheel was influenced with an axle linked to the rear wheel of the motorcycle. They were fitted with a locking differential and selectable street and off-road equipment ratios through which all and invert gears worked well. This made the R75 highly manoeuvrable and with the capacity of negotiating most surfaces. A few other 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 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 upon standardization of parts for both machines, with a view of eventually creating 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. They also agreed that the manufacture of the R75 would cease once production come to 20,200 devices, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.

Since the target of 20,200 BMW R75's had not been reached, it continued to be in production before Eisenach manufacturing plant was so terribly damaged by Allied bombing that creation ceased in 1944. An additional 98 systems were set up by the Soviets in 1946 as reparations.
