No motorcycle manufacturer is more closely associated with one type of engine than BMW: the air-cooled boxer twin or 'airhead'. It was included in BMW's very first motorcycle in 1923 and virtually every machine the company made, of every type, from radical road bike to TT winner, to land speed record holder, to 1970s style icon and even to the creation of an all-new adventure bike class with the R 80 G/S, right up to the mid-1990s.

BMW Airhead Twins, with over 290 photographs, includes a history of the company pre- and post-War, and the personalities behind the development of the bikes. Profiles of each of the 'R' bikes in turn includie detailed specification guides and production numbers. An epilogue that looks to the future of the airhead twins completes the book.
