The BMW R1100 R and R1100S, launched in 1994 and 1998, respectively, represent a significant step in the evolution of BMW's air-cooled boxer engine motorcycles. These models built upon the success of the R850 series, offering increased displacement and a more refined riding experience. While sharing the same 1,085cc air-cooled boxer engine, the R and S models diverge in their intended use and overall character. The R1100R, marketed as a "roadster," prioritizes comfortable, all-around riding with a focus on long-distance touring. It features a relaxed riding position, comfortable ergonomics, and a standard, upright handlebar. On the other hand, the R1100S, marketed as a "sport" model, prioritizes performance and agility. It features a more aggressive riding position, clip-on handlebars, and sportier suspension components designed for spirited riding and precise handling.

Both models are distinguished by their robust construction, featuring a tubular steel frame, Telelever front suspension system, and Paralever rear suspension system, offering excellent handling and stability. The air-cooled boxer engine, renowned for its reliability and characteristic sound, delivers ample power and torque, making both the R and S models capable and enjoyable machines. The R1100 R and S models, along with their successors, the R1150 R and R1150S, solidified BMW's position as a leading manufacturer of versatile and capable motorcycles, catering to a wide range of riding styles and preferences. Their enduring popularity and strong following among enthusiasts speak volumes of their quality, performance, and timeless appeal.
