BMW R-75 is a bike with sidecar and engine with capacity of 7 5 0 cm that was specially designed for military usage. During the period from 1940 to 1944 Company «Bayerische Motoren Werke» in Munich has produced 16,510 of these vehicles. The motorcycle was serviced by a team of two or three people. It had a spare wheel in the sidecar, and compartments for storage of equipment and ammunition. Front part of the sidecar was mounted with a vehicular machine gun MG 34 (with MG 42 later) which provided R-75 with a significant firepower. On the front R-75 was used as a connection machine. It also transported senior officers to the headquarters and back and was used for reconnaissance.
BMW R-75 had a tubular frame. The rear wheel and the wheel of sidecar were driven by a transmission with four front and one rear speeds by means of the chain and drive shaft. It had locking differential and hydraulic brakes on drive wheels, mechanical brakes and \"trouble-free\" telescopic fork on the front wheel. BMW R-75 was not the advanced motorcycle with a telescopic front fork but a hydraulic damper has been applied for the first time exactly on this version. The motorcycle was equipped with gasoline four-stroke, two-cylinder 2.4-liter engine with volume of 46 cc and capacity of 26 hp at 4400 rev. / min.
Reliable gearbox allowed this motorcycle to overcome almost any terrain, making it an excellent vehicle in anticipation of the mass appearance of all-wheel drive biaxial vehicles.
The total mass of the motorcycle was 420 kg (670 kg with a sidecar). The maximum speed on the highway with a sidecar reached 92 km / h. Fuel distance on the road was 340 km, but it was possible to increase it up to 800 km by installing an extra jerry can on the sidecar. Fuel consumption on the road was 9 l per 100 km.
BMW R-75 is probably the best heavy bike of World War II. Technical characteristics of this machine are superior to all motorcycles of belligerents. Many of the technical solutions implemented in BMW R75 were widely used in the post-war German motorcycles.
