The BMW R75 is a World War II-era motorcycle and sidecar mixture made by the German company BMW.

Within the 1930s BMW were creating a variety of popular and highly effective motorcycles. In 1938 development of the R75 were only available in reaction to a get from the German Army.

Preproduction types of the R75 were powered by a 750 cc area valve engine, that was based on the R71 engine motor. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine unit for the R75 product. This OHV engine unit later proved to be the basis for following 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 built in with a locking differential and selectable highway and off-road gear ratios through which all four and invert gears did the trick. This made the R75 highly manoeuvrable and capable of negotiating most surfaces. A few other 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 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 Army, agreed upon standardization of parts for both machines, with a view of eventually creating 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. In addition they agreed that the produce of the R75 would stop once production reached 20,200 products, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.

Since the focus on of 20,200 BMW R75's had not been reached, it continued to be in production before Eisenach stock was so terribly damaged by Allied bombing that development ceased in 1944. A further 98 devices were built by the Soviets in 1946 as reparations.
