The BMW R75 is a global Conflict II-era motorcycle and sidecar combo produced by the German company BMW.
Inside the 1930s BMW were producing a range of popular and impressive motorcycles. In 1938 development of the R75 were only available in response to a question from the German Military.
Preproduction models of the R75 were driven by a 750 cc aspect valve engine, which was based on the R71 engine unit. However it was quickly found necessary to design an all-new OHV 750 cc engine motor for the R75 product. This OHV engine motor later proved to be the foundation for succeeding 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 built in with a locking differential and selectable highway and off-road equipment ratios through which all four and reverse gears proved helpful. 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 own rival the Z?ndapp KS 750 were both broadly employed by the Wehrmacht in Russia and North Africa, though over time of analysis 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 (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 agreed that the make of the R75 would cease once production come to 20,200 devices, and after that point BMW and Z?ndapp would only produce the Z?ndapp-BMW machine, developing 20,000 every year.
Since the concentrate on of 20,200 BMW R75's was not reached, it continued to be in production until the Eisenach manufacturing plant was so terribly destroyed by Allied bombing that development ceased in 1944. A further 98 devices were built by the Soviets in 1946 as reparations.
