The /5 was the first new BMW motorcycle design for nearly two decades, and the basic design would last for more than 25 years. Hans-Gunther von der Marwitz left Porsche in the late 1960s to design the new BMW motorcycles under the wing of technical director Helmut Werner Bonsch. Bonsch had managed to persuade BMW not to abandon motorcycle production altogether in the late 1960s in the mist of the Japanese 'invasion' after the slow demise of the British establishment. In von der Marwitz' mind's eye was a much more modern machine than the previous BMW /2 series in the image of the Featherbed Manx Norton. BMW opened a new motorcycle factory in Spandau, a suburb of Berlin, for the necessary renaissance. Fortunately, success was instant, with 1970 /5 production virtually tripling that of 1969 at 12,287 machines.
BMW, from its completely re-designed, stronger, smoother and vastly more modern motor, quoted 50 horsepower at 6,200rpm for the 4-speed, R75/5, some 10 more than the 600cc R60/5, and 18 more than the 500cc R50/5. With a dry weight of 423lb, the now 12 volt, 745cc, electric start machine was capable of 110mph.
The R50/5 presented here belongs to a large collection of motorcycles located in the surrounds of Toronto. The bike appears to be in original condition, except for the toaster tank, and will gladly return on the roads after having been stored for some time.
