BMW introduced a major innovation to its motorcycle range in 1929. The transverse flat twin engine was already a recognisable BMW feature but for the first time it was installed in a pressed-steel frame, the first models to incorporate this landmark of motorcycle design being the 735cc R11 and R16. BMW's relatively vibration-free engine was already a byword for smoothness and refinement, and this, coupled to a three-speed shaft-drive transmission, made the R11 sidevalve one of the finest touring motorcycles of its day. Progressively improved, the R11 was built in five series up to 1934.
