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

In the 1930s BMW were creating a amount of popular and impressive motorcycles. In 1938 development of the R75 started in reaction to a demand from the German Military.

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

The third side-car wheel was powered with an axle connected to the trunk wheel of the motorcycle. We were holding built in with a locking differential and selectable street and off-road gear ratios through which all and invert gears proved helpful. 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 competitor the Z?ndapp KS 750 were both greatly utilized 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 Army, agreed upon standardization of parts for both machines, with a view of eventually developing a Z?ndapp-BMW hybrid (specified 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 production of the R75 would cease once production come to 20,200 systems, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 every year.

Since the focus on of 20,200 BMW R75's was not reached, it continued to be in production until the Eisenach manufacturing plant was so badly harmed by Allied bombing that production ceased in 1944. A further 98 devices were set up by the Soviets in 1946 as reparations.
