About this model
About the Bmw R 100 S
The BMW R 100 S is a sport-faired twin-cylinder motorcycle powered by a 979 cc air-cooled boxer engine, produced from 1976 to 1984. It was BMW's fastest road motorcycle at the time with 65 hp, fitted with a half-fairing and low handlebar for a more sporty riding position. The typical BMW boxer engine with shaft drive ensures low maintenance costs and long-term reliability. The R 100 S is today a sought-after classic.
The R 100 S targets classic motorcycle enthusiasts who appreciate the combination of sporty riding and BMW heritage. The riding position is sportier than the RT variants but comfortable enough for longer rides. It competes in the classic segment with the Honda CB900F and Kawasaki Z1000. Not for beginners due to age and character. Classic vehicle insurance available for bikes over 30 years old.

Before you buy
What to check before buying
- Check the carburetors for clogging and deteriorated diaphragms; twin boxer carbs require balanced synchronization.
- Inspect the shaft drive for oil leaks; replacing rubber seals is routine maintenance at this age.
- Check the primary chain tension and valve timing; wear is typical when service has been neglected.
- Look for corrosion around the crankshaft seal and generator housing; typical of early R-series engines.
- Ask about parts originality; non-original components significantly affect classic collectible value.
