The BMW R75 is a global War II-era motorcycle and sidecar mixture produced by the German company BMW.
Inside the 1930s BMW were producing a range of popular and highly effective motorcycles. In 1938 development of the R75 were only available in respond to a submission from the German Military.
Preproduction models of the R75 were power by the 750 cc area valve engine, which was predicated on the R71 engine. However it was quickly found essential to design an all-new OHV 750 cc engine unit for the R75 product. 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. These were fixed with a locking differential and selectable road and off-road products ratios through which all four and change gears proved helpful. 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 utilized by the Wehrmacht in Russia and North Africa, though over time 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 Military, agreed after standardization of parts for both machines, with a view of eventually building 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 agreed that the production of the R75 would stop once production come to 20,200 devices, and from then on 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 stock was so badly broken by Allied bombing that production ceased in 1944. A further 98 models were constructed by the Soviets in 1946 as reparations.
