The BMW R75 is a global War II-era motorcycle and sidecar combo made by the German company BMW.
In the 1930s BMW were creating a amount of popular and highly effective motorcycles. In 1938 development of the R75 were only available in response to a submission from the German Military.
Preproduction types of the R75 were run by the 750 cc aspect valve engine, which was predicated on the R71 engine unit. However it was quickly found necessary to design an all-new OHV 750 cc engine for the R75 product. This OHV engine motor 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 connected to the rear wheel of the motorcycle. These were fitted with a locking differential and selectable street and off-road products ratios through which all four and invert gears worked. 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 extensively employed 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 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. In addition they agreed that the manufacture of the R75 would cease once production reached 20,200 units, and from then on point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, processing 20,000 each year.
Since the focus on of 20,200 BMW R75's was not reached, it remained in production until the Eisenach stock was so badly broken by Allied bombing that creation ceased in 1944. An additional 98 models were constructed by the Soviets in 1946 as reparations.
