BMW's motorcycle history began in 1921 when the company commenced manufacturing engines for other companies. BMW's own motorcycles— sold under the BMW Motorrad brand— began in 1923 with the BMW R 32, which was powered by a flat-twin engine (also called a "boxer-twin" engine). Production of motorcycles with flat-twin engines continues to this day, however BMW has also produced many models with other types of engine.
