The first shaft driven GS model was the R80G/S with a 797.5 cc air-cooled, flat-twin boxer engine. The BMW 247 engine, which was also fitted to many other bikes in the BMW range, is known as an airhead. The most valued version was the R80G/S-PD "Paris-Dakar" model featuring a larger tank, which was launched in celebration of the R80G/S wins in the Paris Dakar Rally. In certain markets a 649.6 cc R65GS version was also available. These early machines used a combined rear suspension and drive swingarm called a Monolever.
