BMW R100 RS Mono (1990-1991) Specs, Performance & Photos

In 1990, the German motorcycle manufacturer launched the BMW R100 RS Mono, a touring motorcycle that featured, as its name suggests, a BMW Motorrad Monolever system on the rear.

The 1990 BMW R100 RS Mono was a fully faired touring motorcycle introduced by BMW in 1987, addressed to riders who wanted more power from their machine and the unmistakable sound and feel of a boxer engine.

The 1990 model was in its fourth consecutive year of production, featuring the same package as previous models. It delivered the same technical, visual, and performance specifications without modifications.

Its aesthetic department was characterized by standard features, including 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 the suspension department, the bike packed a hydraulic telescopic fork on the front and a BMW Motorrad Monolever system on the rear, providing optimum suspension performance and handling.

Braking-wise, the bike's wheels were fitted with two 285 mm braking discs tied to dual-piston calipers on the front and a 200 mm drum braking unit on the rear.

As for the power figures, the engine boasted 60 hp at 6,500 rpm and 75 Nm (55 lb-ft) torque at 3,500 rpm from a 980cc four-stroke twin-cylinder air-cooled boxer engine mounted underneath its fuel tank.
