The BMW R75 is a global Conflict II-era motorcycle and sidecar blend produced by the German company BMW.
In the 1930s BMW were creating a range of popular and impressive motorcycles. In 1938 development of the R75 were only available in reaction to a demand from the German Military.
Preproduction models of the R75 were driven with a 750 cc side valve engine, that was based on the R71 engine unit. However it was quickly found essential to design an all-new OHV 750 cc engine motor for the R75 unit. This OHV engine motor later became the foundation for following post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was motivated with an axle linked to the rear wheel of the motorcycle. They were equipped with a locking differential and selectable road and off-road items ratios through which all and invert gears proved helpful. 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 extensively employed 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 upon standardization of parts for both machines, with a view of eventually setting up a Z?ndapp-BMW hybrid (chosen 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 produce 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 each year.
Since the focus on of 20,200 BMW R75's was not reached, it continued to be in production until the Eisenach factory was so badly destroyed by Allied bombing that production ceased in 1944. An additional 98 devices were put together by the Soviets in 1946 as reparations.
