From shortly after their start of motorcycle production in 1923, BMW has been involved in racing. The machines used at this time were performance optimized and derived from the production vehicles.

The königswellen (OHC) machines of the 1930s and 1950s, however, were designed exclusively for racing.

These racing machines with a königswelle engine, be it as a solo machine or as a sidecar, with a long stroke motor and four-speed gearbox or a short stroke motor and five-speed gearbox, with an integrated shaft drive in the right swing arm or a torque arm has moved the world for more than half a century in motorcycle minds.

It passed through a long and successful Grand Prix career, especially gathering great fame in sidecar racing. But many aspects of this period are now in the dark. Its enormous presence in the racing circuit from 1954 to 1974 stands in stark contradiction to its low quantity available.

We decided to write a book about the technical and historic side of the RS. This book will be available in November 2013. The book is a dual language version (German and English) with 144 pages, 120 black and white photos, A4 format (21 by 29 cm), hardcover. The sales price will be 29 Euro plus 8 Euro international shipping.
