BMW R100 RS Mono (1987-1988) Specs, Performance & Photos

In 1987, the German motorcycle manufacturer launched the BMW R100 RS Mono, a touring motorcycle that featured the monolever swingarm introduced in 1986. The 1987 model packed the same specifications as the previous model without modifications.

In the visual department, the bike packed standard fittings, such as a full fairing, a round headlight integrated into the fairing, a windscreen, a one-piece dual seat with a passenger grab handle, a dual chromed exhaust system with a muffler on each side, a center stand, and eight-spoke alloy wheels.

At its core, the 1987 BMW R100 RS Mono had installed a 980cc four-stroke twin-cylinder air-cooled boxer engine fed by two Bing carburetors, delivering an output power of 60 hp at 6,500 rpm and 75 Nm (55 lb-ft) torque at 3,500 rpm.

All the power generated by the engine was converted into motion by a five-speed manual transmission with a dry single-plate clutch that redirected it to the rear end via a final shaft drive, pushing the motorcycle to 189 kph (117 mph).

For suspension, the motorcycle was fitted with a telescopic fork on the front that provided 275 mm of travel and a single-sided swingarm with a right-hand side-mounted shock absorber that offered 121 mm of travel.

As for the braking power, the BMW R100 RS Mono's wheels were fitted with two 285 mm brake discs on the front with dual-piston calipers and a 200 mm drum braking unit mounted on the rear, offering optimum braking performance.
