The BMW R1100S, produced from 1999 to 2005, was a groundbreaking motorcycle that pushed the boundaries of sport touring. Building upon the success of the R1100RS, the R1100S adopted a more aggressive and sporty aesthetic. Its sleek, low-slung profile, featuring a half-fairing and a single-sided swingarm, exuded a dynamic and modern design, a stark contrast to the traditional BMW touring bikes of the time. The heart of the R1100S was its 1,085cc air-cooled boxer engine, a hallmark of BMW motorcycles. This engine, known for its smooth power delivery and durability, was tuned for performance, generating a respectable 98 horsepower and 78 lb-ft of torque. The combination of a powerful engine and a relatively lightweight chassis, weighing in at 485 lbs, resulted in an exhilarating riding experience that balanced agility with stability. The R1100S was equipped with a host of technological innovations for its time. It featured a sophisticated suspension system with a fully adjustable front fork and a rear shock absorber, providing excellent handling and a comfortable ride. The braking system relied on twin 320mm discs up front and a single 276mm disc at the rear, offering strong stopping power even at high speeds. The R1100S also boasted a comprehensive instrumentation panel, including a speedometer, tachometer, fuel gauge, temperature gauge, and a digital clock. With its exceptional combination of performance, handling, comfort, and features, the BMW R1100S became a favorite among riders seeking a sporty and capable motorcycle for both daily commutes and weekend adventures. Its unique styling and innovative design cemented its place as a significant milestone in BMW's storied history, paving the way for future sport touring models like the R1200S and the S1000RR.
