M72 motorcycle
The M72 ("M" for "Motozikl", Russian Мотоцикл for motorcycle) was a motorcycle from Soviet production. It was manufactured from 1941 to 1957 in the Irbiter motorcycle works and was used very often as a motorcycle combination with a replica of the German Steib TR500 official sidecar . In the first years of construction, the M72 was a detailed copy of the German BMW R 71 , which had been produced from 1938 to 1941.
The motor M 72 is a side-controlled 2-cylinder four-stroke cycle - Boxer engine square design (bore and stroke are the same) 78 × 78 mm. The maximum output is 16 kW (22 hp) at 4950 rpm. Ready for operation, the motorcycle weighs approx. 220 kg, as a team approx. 350 kg. The maximum load as a team is 250 kg.
The M72 was developed by the Red Army in World War II used as all-terrain vehicle. However, since it turned out to be unsuitable for difficult terrain, the M72 was soon improved, including: New air filter with oil filling, higher front fender and rear fender bracket for easier opening of the fender to facilitate wheel changes and gusset plates on the rear shock absorber mount. The gusset plates had become necessary because the frame breaks more frequently under operating conditions.
The Ural and Dnepr brands were later developed on the basis of the M72 .
