The BMW R75 is a global Warfare II-era motorcycle and sidecar combo produced by the German company BMW.
Within the 1930s BMW were producing a quantity of popular and impressive motorcycles. In 1938 development of the R75 started in reaction to a demand from the German Military.
Preproduction models of the R75 were power by a 750 cc area valve engine, which was predicated on the R71 engine unit. However it was quickly found necessary to design an all-new OHV 750 cc engine motor for the R75 unit. This OHV engine motor later became the foundation for succeeding 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 trunk wheel of the motorcycle. We were holding equipped with a locking differential and selectable street and off-road equipment ratios by which all and reverse gears worked well. This made the R75 highly manoeuvrable and with the capacity of negotiating most floors. Additional 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 extensively 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 after standardization of parts for both machines, with a view of eventually making a Z?ndapp-BMW hybrid (designated the BW 43), when a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. They also agreed that the produce of the R75 would cease once production come to 20,200 units, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 every year.
Since the goal of 20,200 BMW R75's was not reached, it continued to be in production until the Eisenach manufacturing plant was so terribly broken by Allied bombing that production ceased in 1944. A further 98 systems were assembled by the Soviets in 1946 as reparations.
