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). Max [[torque]] was 56.06 ft/lbs (76.0 Nm) @ 6000 RPM. Claimed [[horsepower]] was 58.74 HP (43.8 KW) @ 6500 RPM.  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 [[BMW R32|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 [[marque]]s, 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 integral 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.
