Formed in 1916, BMW (Bavarian Motor Works) began producing truck and aircraft engines for Germany during WWI, with post-war production focused on the motorcycle. BMW Motorrad, as the two-wheeled division of BMW came to be known (motorrad is German for motorcycle), traces its origins to the R32 motorcycle produced in 1923. Since then numerous models have been produced, including the popular R1200GS along with host of other bikes sourcing the Boxer powerplant. The K series features a four-cylinder engine and BMW Motorcycles enters the superbike market with its S1000RR literbike. BMW Motorcycles has also developed a versatile off-road and street lineup with Single G and Parallel Twin F series. History of BMW Motorcycles
