The BMW R75 is a World War II-era motorcycle and sidecar blend produced by the German company BMW.
In the 1930s BMW were producing a range of popular and impressive motorcycles. In 1938 development of the R75 were only available in response to a get from the German Army.
Preproduction models of the R75 were driven by the 750 cc side 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 device. This OHV engine unit later became the foundation for subsequent post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was powered with an axle linked to the trunk wheel of the motorcycle. These were fixed with a locking differential and selectable street and off-road products ratios by which all and reverse gears proved helpful. This made the R75 highly manoeuvrable and capable 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 greatly used by the Wehrmacht in Russia and North Africa, though over time 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 making 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 arranged that the manufacture of the R75 would stop once production come to 20,200 units, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.
Since the concentrate on of 20,200 BMW R75's was not reached, it remained in production before Eisenach manufacturing plant was so terribly harmed by Allied bombing that creation ceased in 1944. A further 98 items were built by the Soviets in 1946 as reparations.
