The BMW R100RS was a two cylinder boxer, four-stroke Touring motorcycle produced by BMW between 1976 and 1989. It could reach a top speed of 116 mph (186 km/h).

The R100RS, was heralded as "the most radical-looking motorcycle the modern market has ever seen" quite an accomplishment for stodgy BMW.


History

BMW, normally a highly conservative motorcycle company, with very infrequent model changes, and its devotion to its original concept (BMW has used transverse flat-twin power units since the first R32 was built in 1923) could lay the Munich firm open to the accusation that it doesn't innovate. However, nothing could be further from the truth. BMW has often headed some of tile most dramatic developments in the evolution of motorcycles.

Logical Evolution

In contrast to the Japanese marques, BMWs strategy is not to emulate successes but to concentrate on the logical, functional evolution of its models. They create without copying. One of their most fundamental steps was made in 1976 with the launch of the R100 RS, a sports/grand touring bike where, for the first time on a machine produced in large numbers, the fairing was not just a bolt on accessory but an int=egral part of the bike.

=Integral Fairing

Curiously enough , throughout motorcycling history fairings (at first a simple aluminum shell, then a fiberglass molding, and now made from plastics) and frames have always been poorly integrated. With the BMW R100 RS, the ABS fairing became for the first time an integral part of the machine. There was a high level of Finish on its internal Face including a fully equipped instrument panel and excellent aerodynamics developed in the wind tunnel. The tunnel trials enhanced the bike's performance while giving the rider levels of comfort and protection which remain the standard today.


Engine

The engine was a air cooled two cylinder boxer, four-stroke. A 94.0mm bore x 70.6mm stroke result in a displacement of just 979.0 cubic centimeters. Fuel was supplied via a overhead valves (ohv).

Drive

The bike has a 5-speed transmission. Power was moderated via the dry, single plate, diaphragm spring.

Chassis

It came with a 90/90-18 front tire and a 120/90-18 rear tire. Stopping was achieved via dual disc in the front and a expanding brake in the rear. The front suspension was a hydraulic telescopic fork while the rear was equipped with a dual adjustable shocks. The R100RS was fitted with a 5.81 Gallon (22.00 Liters) fuel tank. The wheelbase was 57.72 inches (1466 mm) long.
