BMW R 100RS (1976)

The BMW R 100RS, the ultimate sports tourer, boasts a sleek fairing designed to conquer the elements, not just the road. Powered by a 980cc horizontally opposed, twin-cylinder engine, it develops a respectable 70bhp at 7250 rpm.

This impressive powerplant is mated to a pair of 40mm Bing carburetors, providing a smooth and responsive ride. The result is a bike capable of reaching speeds of up to 125mph, although the large fairing does impose some limitations.

But the R 100RS is more than just a fast machine – it’s a comfortable and practical proposition for high-speed touring. The fairing, designed with the expertise of Pininfarina, is a masterpiece of aerodynamics, deflecting wind and rain around the rider with ease. Riding the R 100RS is an exhilarating experience, one that combines the thrill of the ride with the security of a well-designed machine. It’s a bike that defies logic, but one that has proven its quality and dependability time and time again.
