The BMW R75 is a global Warfare II-era motorcycle and sidecar blend produced by the German company BMW.
Within the 1930s BMW were creating a amount of popular and highly effective motorcycles. In 1938 development of the R75 started in response to a submission from the German Military.
Preproduction models of the R75 were run by a 750 cc side valve engine, which was predicated on the R71 engine. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine motor for the R75 product. This OHV engine later became the basis for following post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was driven with an axle linked to the rear wheel of the motorcycle. These were installed with a locking differential and selectable road and off-road equipment ratios through which all and reverse gears did the trick. 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 rival the Z?ndapp KS 750 were both greatly 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 Army, agreed after standardization of parts for both machines, with a view of eventually developing a Z?ndapp-BMW hybrid (designated the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also agreed that the manufacture of the R75 would cease once production come to 20,200 products, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 every year.
Since the goal of 20,200 BMW R75's had not been reached, it remained in production before Eisenach manufacturing plant was so terribly broken by Allied bombing that creation ceased in 1944. A further 98 devices were built by the Soviets in 1946 as reparations.
