BMW

BMW began building motorcycle engines and then motorcycles after World War I. Its motorcycle division is now known as BMW Motorrad. Their first successful motorcycle, after the failed Helios and Flink, was the "R32" in 1923. This had a "Boxer" twin engine, in which an ICCE cylinder protrudes into the air-flow from each side of the machine. Apart from their singles (basically to the same pattern), all their motorcycles had used this distinctive layout until the early 1980s. Many BMWs are still produced to this pattern, which is designated the R Series.

BMW has been an innovator in motorcycle suspension design, taking up telescopic front suspension long before most other manufacturers. Then they switched to Earles Fork, front suspension by swinging fork (1955 to 1969). Most modern BMWs are truly rear swingarm, single sided at the back (compare with the regular swinging fork usually, and wrongly, called swinging arm).

Some BMWs started using yet another trademark front suspension design, the Telelever, in the early 1990s. Like the Earles Fork, the Telelever significantly reduces dive under braking.
