BMW began production of motorcycle engines and then motorcycles after World War I. Its motorcycle brand is now known as BMW Motorrad. Their first successful motorcycle after the failed Helios and Flink, was the "R32" in 1923, though production originally began in 1921. This had a "boxer" twin engine, in which a cylinder projects into the air-flow from each side of the machine. Apart from their single-cylinder models, all their motorcycles used this distinctive layout until the early 1980s. Many BMW's are still produced in this layout, which is designated the R Series.
