Bmw R 1100 S
The BMW R 1100 S was introduced in 1998 as a sport-oriented boxer twin, representing BMW's most performance-focused motorcycle at the time. It featured a revised 1085cc air/oil-cooled boxer engine, Telelever front suspension, and aggressive styling that set it apart from BMW's touring lineup. The R 1100 S was produced until 2005 and earned a strong following for its unique blend of character, handling, and long-distance capability, later giving way to the R 1200 S.

What Buyers Should Know
Boxer Engine Durability
The air/oil-cooled 1085cc Boxer twin is known to last well beyond 100,000 miles with proper maintenance. Regular valve clearance checks and timely oil changes are the keys to longevity.
Watch the Throttle Bodies
A common issue on the R 1100 S is worn throttle body shaft seals causing rough idle and poor fueling. Always test ride for hesitation or uneven throttle response before buying.
Strong Resale & Collectibility
Produced only from 1999–2005, the R 1100 S is increasingly sought after as a modern classic, helping it hold value better than many bikes of its era. Clean low-mileage examples continue to appreciate.
