The BMW R75 is a World Conflict II-era motorcycle and sidecar combination produced by the German company BMW.
Inside the 1930s BMW were creating a range of popular and highly effective motorcycles. In 1938 development of the R75 were only available in response to a request from the German Army.
Preproduction models of the R75 were driven by way of a 750 cc area valve engine, that was based on the R71 engine motor. However it was quickly found essential to design an all-new OHV 750 cc engine for the R75 unit. This OHV engine motor later proved to be the basis for following post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was driven with an axle connected to the rear wheel of the motorcycle. We were holding built in with a locking differential and selectable highway and off-road products ratios by which all four and change gears worked. This made the R75 highly manoeuvrable and with the capacity of negotiating most floors. A few other 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 greatly 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 upon standardization of parts for both machines, with a view of eventually making a Z?ndapp-BMW hybrid (selected 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 production of the R75 would cease once production reached 20,200 devices, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 each year.
Since the concentrate on of 20,200 BMW R75's was not reached, it continued to be in production before Eisenach stock was so badly broken by Allied bombing that creation ceased in 1944. An additional 98 items were constructed by the Soviets in 1946 as reparations.
