BMW R1100S (2003-2004) 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.

In 2003, the German motorcycle maker released the BMW R1100S, a sport-touring motorcycle in its sixth consecutive production year. The 2003 motorcycle featured some modifications to the engine.

The engines produced since 2003 had dual ignition with two spark plugs per cylinder. The bike's transmission was derived from the BMW K1200RS, and the top gear offered 32 kph (20 mph) per 1,000 rpm.

In the visual department, the bike was similar to the previous one, packing the same 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.

As for the power figures, the 2003 BMW R1100S boasted 98 hp with a peak force at 7,500 rpm and 95 Nm (70 lb-ft) torque at 7,500 rpm from a 1,085cc four-stroke air/oil-cooled twin-cylinder boxer engine with a fuel injection system in charge.

A six-speed manual gearbox with a dry single-plate clutch as a final shaft drive redirected the power from the engine to the rear wheel, pushing the bike to a top speed of 219 kph (136 mph).
