BMW R100 RS Mono (1989-1990) Specs, Performance & Photos

The BMW R100 RS Mono was a fully faired touring motorcycle introduced by BMW in 1987, packing, as its name suggests, a monolever suspension system on the rear represented by a single-sided swingarm coupled to a single-sided rear shock absorber.

In 1989, the German motorcycle manufacturer launched the BMW R100 RS Mono, a touring motorcycle addressed to riders who wanted more power from their machine and the unmistakable sound and feel of a boxer engine.

The 1989 motorcycle was delivered with the same package as previous models, offering the same technical, visual, and performance specifications without any significant modifications whatsoever.

In the visual department, the bike had 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.

In terms of power, the 1989 BMW R100 RS Mono took its muscles from a 980cc four-stroke twin-cylinder air-cooled boxer engine mounted underneath its fuel tank, boasting 60 hp at 6,500 rpm and 75 Nm (55 lb-ft) torque at 3,500 rpm.

As for safety, the bike's eight-spoke aluminum wheels were fitted with two 285 mm brake discs on the front, dual-piston calipers, and a 200 mm drum braking unit mounted on the rear, offering optimum braking performance.
