BMW R 1100 S 2002 — Specifications

Can you really make a sportbike with a flat-twin? BMW answered that question between 1998 and 2005 with the R 1100 S, and the answer is more nuanced than a simple yes. The BMW R 1100 S doesn't play in the same league as a Honda CBR or a Suzuki GSX-R. Where the Japanese bikes bank on fury and high revs, the German prefers the gentleman rider's score. Its 1085 cc boxer twin produces 98 hp at 7500 rpm and, more importantly, 97 Nm of torque from just 5750 rpm. The kind of power that doesn't scream but pushes hard, with a generous usable range between 3000 and 5000 rpm. Beyond that, the thrust fades. It's not meant to rival an inline four-cylinder in the upper rev range, but to pull with authority on the stretches of road where torque rules.

In terms of styling, the 2002 BMW R 1100 S remains one of Munich's finest offerings. The front-end design, both taut and muscular, contrasts with a slim, aggressive tail. The Paralever single-sided swingarm and the twin underseat exhaust outlets echo the hallmarks of Italian sportbikes of the era. A certain Ducati 996 comes to mind, and the comparison isn't unwarranted. The BMW R 1100 S Boxer Cup version, developed for the eponymous one-make racing series, pushes the temperament dial even further. But in standard trim, the machine clearly positions itself as a sport-tourer. Much like the Honda VFR 800 of the same era, it aims for versatility rather than outright performance.

The chassis, built around a cast aluminum front frame and a steel rear subframe, displays thorough Bavarian rigor. The Telelever front suspension delivers predictable, confidence-inspiring handling, with fork adjustment available via a dial accessible from the cockpit. Stability is its strong suit. In fast corners, the BMW R 1100 S inspires total confidence. Comfort is well preserved, far from the harshness of a hypersport. On the other hand, in tight low-speed transitions, its 245 kg wet weight makes itself known. Nimbleness is not its preferred playground. The Brembo braking system, with twin front discs, proves powerful and progressive. Wind protection lives up to its promises up to 180 km/h, which covers the vast majority of road riding scenarios.

The main criticism leveled at this generation concerns the flat-twin's vibrations, noticeable on long rides and a recurring topic of discussion on BMW R 1100 S forums. This BMW R 1100 S issue is well known and documented, though far from a deal-breaker. The shaft drive and six-speed gearbox deliver fuss-free operation, typical of the BMW philosophy. With an 18-liter tank and a seat height of 800 mm, range and accessibility remain respectable for a sport-tourer of this size.

Today, a used BMW R 1100 S represents an appealing proposition for anyone seeking a sporty tourer with strong character. BMW R 1100 S models from 1998 to 2005 trade at reasonable prices, well below the 12,600 euros asked when new. Some owners convert theirs into a BMW R 1100 S cafe racer, proof that the mechanical and aesthetic foundation lends itself to it. The BMW R 1100 S test confirms what BMW R 1100 S reviews have been saying for years: it's an endearing, honest machine that ages gracefully. Not the fastest with its 226 km/h top speed, not the lightest, but a motorcycle with character that looks like nothing else. Randy Mamola himself, ambassador of the BMW R 1100 S Randy Mamola edition, was not mistaken. For boxer enthusiasts, it remains a safe bet.
