The BMW R 1100 S, introduced in 2002 and produced until 2006, was a radical departure from the traditional BMW touring and adventure motorcycles. It was a sport-focused, high-performance machine designed to compete directly with Japanese rivals like the Honda CBR900RR and Yamaha R1. The R 1100 S featured a lightweight aluminum frame, a powerful air-cooled, 1,085cc boxer engine, and aggressive styling. This engine was an evolution of the boxer powerplant used in the R 1100 GS, tuned for higher revs and more power. With 98 horsepower and a top speed of over 140 mph, the R 1100 S was a true performance machine.

Although the R 1100 S shared some components with the GS, it was a completely different motorcycle in terms of handling and performance. The suspension was designed for aggressive cornering, featuring inverted telescopic forks upfront and a single-sided swingarm with a monoshock in the rear. The R 1100 S was also equipped with a more advanced braking system featuring dual 320mm discs up front with four-piston calipers. Its aggressive styling, sharp lines, and low-slung profile further emphasized its sport-focused nature. The R 1100 S was praised for its handling and performance, but it was also criticized for its harsh ride and lack of practicality compared to other BMW models. Nevertheless, it proved to be a successful model for BMW and helped establish the company as a serious contender in the sportbike segment, paving the way for the even more powerful and refined R 1200 S that followed.
