The BMW R75 is a World War II-era motorcycle and sidecar combination produced by the German company BMW.
In the 1930s BMW were producing a quantity 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 part valve engine, that was predicated on the R71 engine. However it was quickly found essential to design an all-new OHV 750 cc engine motor for the R75 product. 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 connected to the trunk wheel of the motorcycle. They were built in with a locking differential and selectable highway and off-road products ratios through which all and change gears proved helpful. This made the R75 highly manoeuvrable and capable of negotiating most floors. 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 broadly employed 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 Military, agreed upon standardization of parts for both machines, with a view of eventually developing 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 agreed that the produce of the R75 would stop once production reached 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 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. An additional 98 units were constructed by the Soviets in 1946 as reparations.
