The BMW R75 is a World Warfare II-era motorcycle and sidecar blend produced by the German company BMW.
Inside the 1930s BMW were producing a quantity of popular and impressive motorcycles. In 1938 development of the R75 started in reaction to a submission from the German Army.
Preproduction types of the R75 were driven by way of a 750 cc area valve engine, that was predicated on the R71 engine. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine unit for the R75 product. This OHV engine later became the foundation for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was driven with an axle connected to the trunk wheel of the motorcycle. We were holding fixed with a locking differential and selectable road and off-road products ratios by which all four and change gears functioned. 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 rival the Z?ndapp KS 750 were both extensively 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 Army, agreed after standardization of parts for both machines, with a view of eventually creating a Z?ndapp-BMW hybrid (designated 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 manufacture of the R75 would cease once production reached 20,200 items, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 each year.
Since the aim for of 20,200 BMW R75's had not been reached, it remained in production until the Eisenach factory was so badly broken by Allied bombing that production ceased in 1944. An additional 98 models were constructed by the Soviets in 1946 as reparations.
