Max Frizs R32 of 1923, the first BMW boxer twin motorcycle, set BMW on a path that would continue for the next 80 years. Although the twin has predominated, some of the most popular BMW motorcycles have been singles and the K-series triples and fours. BMW has never been afraid of innovation, from the supercharger ot the 1920s and 1930s, the telescopic then Earles fork, wind-tunnel-developed fairings, anti-lock brakes and Paralever swingarms. Here is the full story of all the BMW road and racing machines, and the people who designed them, including classic machines such as the Kompressor, RS54, R69S, R90S, and R100RS, as well as the latest R1150 and K1200.
