BMW R1100S (1999-2000) Specs, Performance & Photos

The BMW R1100S was a sports or sports-touring motorcycle manufactured by BMW from 1998 until 2005 when it was replaced by the BMW R1200S. It was introduced 25 years after BMW's first sports bike, the R90S, and was the first BMW motorcycle that featured a clip-on handlebar, rear set footrests, and a removable passenger seat cover.

In 1999, the German motorcycle manufacturer launched the BMW R1100S, a sports machine 27 kg (60 lbs) lighter and 8 hp more powerful than the BMW R1100RS. At 229 kg (505 lbs), it wasn't considered a lightweight sports machine.

The motorcycle's visual department had standard fittings, such as a half fairing with integrated turn signals, a single headlight unit, a windscreen, a one-piece dual seat with a removable passenger seat cover, a center stand, and five-spoke aluminum wheels.

As for the power figures, the 1999 BMW R1100S had installed a 1,085cc four-stroke air/oil-cooled twin-cylinder boxer engine that delivered an output power of 98 hp with a peak force at 7,500 rpm and 97 Nm (72 lb-ft) torque at 5,750 rpm.

The braking power was achieved by two 320 mm brake discs on the front wheel and a 276 mm brake disc on the rear. The front ones were engaged by four-piston calipers, while the rear one was squeezed by a dual-piston caliper.
