The origins of BMW are now almost 100 years old. And so many, but not all BMW design elements were set for decades to come. This was about six years after Norton began experimenting with it on the Manx road racer. In 1936 came the tubular frame and in 1938 the telescopic, or “plunger” rear suspension. In 1955 the traditional swing-arm design frame became standard for all production street bikes. In 1935 the telescopic fork replaced the leading link fork for the new R12 and R17, but just for awhile. Over time five versions of the R11 were made with this machine, a 1934 model, being the final.Ī little early BMW chassis history: Continued development had brought the introduction of the interesting pressed steel frame in 1929. The engine featured sealed lubrication, was not “total loss” like most manufacturers were still using. The R32 had its opposed twin engine mounted with its crankshaft in line and used a three-speed transmission through an open drive-shaft. But then he helped engineer the new model R32 motorcycle shown at the 1932 Paris Motor Show. Friz’s focus was designing aircraft engines. Max Friz was the Chief Design Engineer starting with the company, Bavarian Motor Works at its inception in 1916. In the years leading up to 1921, a couple of years before BMW began to make motorcycles in 1923, they were supplying “boxer” twin engines to airplane as well as other motorcycle manufacturers.
