BMW acted to simplify the system in the mid-1920s. The references to the number of cylinders and model series were abandoned. Now the only entry in front of the project number was to denote an engine (‘M’ = Motor), transmission (‘G’ = Getriebe), a frame for motorcycles (‘R’ = Rahmen) or a chassis for cars (‘F’ = Fahrgestell).And this was how the first ever BMW motorcycle got its name. The frame for the new bike was given the project number ‘R 32’ when it was entered into the project list. The engine was christened ‘M2B33’, later shortened to ‘M33’. The transmission used in the motorcycle bore the designation ‘G 34’. The internal project number for the frame construction saw the motorcycle unveiled with the official sales designation ‘BMW R 32’. Initially, all the brand’s motorcycles were issued with their name according to this system, a product of the design organisation. In the public use, the ‘R’ stands for ‘Rad’, a short name for Motorrad (=motorcycle) at this time. Interestingly, many mistake ‘Rad’ for the other sense of the word – ‘wheel’!
