BMW R 100 RS 1979



Who would call BMW "trend setting?" Even as motorcycles in general have become bigger, faster, more complex with more and more cylinders and valves and carburetors or even computer-controlled fuel injection, BMWs have come with the same basic engine layout since 1923—opposed Twin, two valves per cylinder, push-rods, two carburetors and a driveshaft to deliver power to the rear wheel.
