BMW R1100S (2005-2006) Specs, Performance & Photos

The BMW R1100S was a sports or sports-touring motorcycle made 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.

When it was replaced by the R1200S in 2005, the R1100S's alloy frame was replaced by a lightweight trellis unit and a tuned engine. The new frame combined with the tuned engine resulted in 13 kg (29 lbs) less and 25 percent more power.

In 2005, the German motorcycle maker released the BMW R1100S, a sport-touring motorcycle in its last production year. It remained largely unchanged over its production period, offering the same specifications without significant modifications.

The bike's appearance was complemented by standard features, such as a half fairing with a windscreen, a one-piece dual seat with a passenger seat cover, an under-seat exhaust system, a single-sided swingarm, and five-spoke aluminum wheels.

The 2005 BMW R1100S was powered by a 1,085cc four-stroke air/oil-cooled twin-cylinder boxer engine, managed by a fuel injection system. It delivered an output power of 98 hp at 7,500 rpm and 95 Nm (70 lb-ft) torque at 7,500 rpm.

As for the stopping power, the motorcycle relied on two 320 mm brake discs mounted on the front wheel and a 276 mm brake disc mounted on the rear wheel. The front ones were coupled to four-piston calipers, while the rear was tied to a dual-piston caliper.
