The BMW R75 is a World Warfare II-era motorcycle and sidecar combination produced by the German company BMW.
Within the 1930s BMW were creating a volume of popular and impressive motorcycles. In 1938 development of the R75 were only available in reaction to a get from the German Military.
Preproduction models of the R75 were power by 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 unit for the R75 device. This OHV engine later proved to be the foundation for subsequent 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 trunk wheel of the motorcycle. These were fixed with a locking differential and selectable highway and off-road items ratios through which all and change gears worked. This made the R75 highly manoeuvrable and capable 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 generally utilized 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 after standardization of parts for both machines, with a view of eventually making a Z?ndapp-BMW hybrid (selected 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 make of the R75 would cease once production come to 20,200 items, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, manufacturing 20,000 every year.
Since the target of 20,200 BMW R75's had not been reached, it continued to be in production before Eisenach stock was so badly ruined by Allied bombing that production ceased in 1944. An additional 98 systems were put together by the Soviets in 1946 as reparations.
