The BMW R75 is a World Conflict II-era motorcycle and sidecar blend produced by the German company BMW.
Inside the 1930s BMW were producing a number of popular and highly effective motorcycles. In 1938 development of the R75 started in response to a need from the German Military.
Preproduction types of the R75 were run by way of a 750 cc side valve engine, which was based on the R71 engine motor. Nonetheless it was quickly found essential to design an all-new OHV 750 cc engine motor for the R75 device. This OHV engine later became the basis for subsequent 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. These were fixed with a locking differential and selectable highway and off-road items ratios through which all four and change gears did the trick. This made the R75 highly manoeuvrable and with the capacity of negotiating most surfaces. A few other 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 widely employed by the Wehrmacht in Russia and North Africa, though after a period 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 building 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. In addition they arranged that the produce of the R75 would stop once production reached 20,200 items, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, making 20,000 every year.
Since the concentrate on of 20,200 BMW R75's was not reached, it continued to be in production before Eisenach manufacturing plant was so terribly ruined by Allied bombing that production ceased in 1944. A further 98 models were set up by the Soviets in 1946 as reparations.
