BMW R2 1931


BMW R2 from the first year of this model's production, 1931 (R2 Series 1). The BMW R2 was a 198 cc overhead valve single-cylinder motorcycle produced by BMW between 1931 and 1936, the smallest motorcycle ever built by BMW company. Despite its much smaller design and engine capacity, the R2 retained many features of the larger boxer twin motorcycles in the range, such as cardan shaft drive and a pressed-steel duplex frame. The R2 was the smallest in the range of singles produced during the 1930s by BMW, with its big brothers being the 305 ccR3 and the 400 cc R4.

[img]R2 Series 1, produced only in 1931, was the only model to feature exposed valve springs on the top of the finned cylinder head. Its maximum power was 6 HP (after British Amal carburetor was introduced in 1933, power output was boosted to to 8 hp). It had 3 gears and 6-Volt electrical system with a Bosch generator. Fuel consumption was 2,75 litres per 100 km, and maximum speed - 95 kph (59 mph). Production number for R2 Series 1 was 4161 units, and overall production of R2 model was 15207 units.

„Following the collapse of the Weimar Republic economy during the Wall Street Crash of 1929, BMW's premier large capacity, expensive motorcycle range was hard hit, with fewer customers now being able to afford their premium purchase costs. BMW therefore felt the need to introduce a smaller bike into their range, which offered both cheaper purchase costs and less expensive running costs. The firm also wished to expand their range in order to make a bike available to riders who did not hold a motorcycle licence, which was not required for bikes under 200 cc.This led to the R2's introduction in 1931 in the form of the Series 1, of which 4,161 units were sold during its one year production run until the introduction of the improved Series 2A the following year. It was known as the "people's bike", and was priced at 975 RM, compared to 1,750 RM for the 750 cc flat-twin R11 Series 2 of the same year...” from Wikipedia
