The beginning was an event that occurred January 2, 1917: the day 33-year-old engineer Max Friz began his work at BMW. Shortly before that he had resigned from their previous work, selling of opinion with his boss Paul Daimler in Stuttgart. As it turned out, it was on hand BMW. In fact, after the ban on the construction of aircraft and aircraft engines under the Versailles Treaty of June 28, 1919 the very existence of BMW was put into question. Then Max Fritz, meanwhile became chief designer for BMW, with the head went in to work on motorcycles. Already in December 1922, just four weeks after receipt of order, Fritz was ready drawing the BMW in the original size. The heart of it was a new drive concept - BMW boxer engine combined with a driveshaft. Ingenuity Schwab Max Friz managed to create a harmonious concept motorcycle, bringing together well-known components and placing them in a new way. Both cylinder boxer engine installed longitudinally not like most other manufacturers, and across the direction of travel, which contributed to their better cooling ram air. The box was docked to the motor and the drive is done directly from the longitudinal arrangement of the crankshaft. Instead of the usual chain drive BMW in the first direct transfer of torque to the rear wheels provide driveshaft. These three components of the basic concept of BMW motorcycles well proven for well over 75 years and is still used in modern opposing models.
