The BMW R75 is a World Warfare II-era motorcycle and sidecar blend made by the German company BMW.
Inside the 1930s BMW were producing a amount of popular and impressive motorcycles. In 1938 development of the R75 started in reaction to a request from the German Army.
Preproduction types of the R75 were run by a 750 cc aspect valve engine, which was predicated on the R71 engine motor. However it was quickly found essential to design an all-new OHV 750 cc engine unit for the R75 product. This OHV engine later became the basis for subsequent post-war twin BMW engines like the R51/3, R67 and R68.
The third side-car wheel was driven with an axle connected to the rear wheel of the motorcycle. These were equipped with a locking differential and selectable road and off-road gear ratios by which all four and invert gears did the trick. This made the R75 highly manoeuvrable and with the capacity of negotiating most surfaces. Additional motorcycle manufactures, like FN and Norton, provided an optional drive to sidecars.
The BMW R75 and its rival the Z?ndapp KS 750 were both generally employed by the Wehrmacht in Russia and North Africa, though over time of evaluation 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 creating 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 decided that the production of the R75 would cease once production come to 20,200 devices, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.
Since the focus on of 20,200 BMW R75's had not been reached, it remained in production before Eisenach manufacturing plant was so terribly harmed by Allied bombing that creation ceased in 1944. An additional 98 units were constructed by the Soviets in 1946 as reparations.
