The BMW R75 is a global Battle II-era motorcycle and sidecar combination produced by the German company BMW.
In the 1930s BMW were creating a volume of popular and impressive motorcycles. In 1938 development of the R75 were only available in reaction to a submission from the German Army.
Preproduction types of the R75 were power by a 750 cc aspect valve engine, which was predicated on the R71 engine motor. Nonetheless it was quickly found essential to design an all-new OHV 750 cc engine unit for the R75 unit. This OHV engine motor later became the basis for succeeding 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. These were built in with a locking differential and selectable road and off-road gear ratios through which all four and invert gears did the trick. This made the R75 highly manoeuvrable and with the capacity of negotiating most areas. A few other 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 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 Military, agreed after standardization of parts for both machines, with a view of eventually setting up 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 produce of the R75 would stop once production come to 20,200 models, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 every year.
Since the concentrate on of 20,200 BMW R75's was not reached, it remained in production until the Eisenach stock was so badly damaged by Allied bombing that development ceased in 1944. An additional 98 products were assembled by the Soviets in 1946 as reparations.
