The BMW R75 is a World Warfare II-era motorcycle and sidecar combination made by the German company BMW.
Within the 1930s BMW were producing a variety of popular and highly effective motorcycles. In 1938 development of the R75 were only available in respond to a question from the German Army.
Preproduction types of the R75 were powered by way of a 750 cc aspect valve engine, that was predicated on the R71 engine. Nonetheless it was quickly found necessary to design an all-new OHV 750 cc engine for the R75 product. This OHV engine unit later became the foundation for succeeding post-war twin BMW engines like the R51/3, R67 and R68.
The 3rd side-car wheel was driven with an axle linked to the rear wheel of the motorcycle. They were fitted with a locking differential and selectable road and off-road equipment ratios through which all and change gears functioned. This made the R75 highly manoeuvrable and capable of negotiating most areas. 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 broadly utilized 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 Military, agreed after standardization of parts for both machines, with a view of eventually building a Z?ndapp-BMW hybrid (chosen the BW 43), in which a BMW 286/1 side-car would be grafted onto a Z?ndapp KS 750 motorcycle. In addition they arranged that the manufacture of the R75 would stop once production come to 20,200 products, 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 had not been reached, it continued to be in production before Eisenach factory was so terribly destroyed by Allied bombing that development ceased in 1944. An additional 98 products were constructed by the Soviets in 1946 as reparations.
