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

Within the 1930s BMW were producing a quantity of popular and highly effective motorcycles. In 1938 development of the R75 started in response to a need from the German Military.

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

The third side-car wheel was motivated with an axle connected to the rear wheel of the motorcycle. These were fixed with a locking differential and selectable street and off-road gear ratios through which all four and change gears performed. This made the R75 highly manoeuvrable and with the capacity of negotiating most areas. 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 extensively employed 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 after standardization of parts for both machines, with a view of eventually building a Z?ndapp-BMW hybrid (chosen the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also decided that the production of the R75 would cease once production come to 20,200 devices, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 every year.

Since the aim for of 20,200 BMW R75's was not reached, it continued to be in production until the Eisenach stock was so badly ruined by Allied bombing that production ceased in 1944. A further 98 models were constructed by the Soviets in 1946 as reparations.
