BMW's /7 (slash 7) series, introduced for the 1977 model year, was the final and most refined version of the traditional air-cooled boxer twin before major platform changes. The lineup included the R60/7, R75/7, R80/7, and the range-topping 980cc R100 variants. The most significant model was the R100RS, which featured the world's first full fairing on a production motorcycle, establishing the sport-touring category.
Collectors value the /7 for its legendary durability, straightforward mechanicals, and exceptional parts support. These bikes are known for being easy to work on and capable of covering huge distances with regular maintenance, making them practical classics. Desirable models include the faired R100RS and R100RT, the sporty R100S, and special editions like the R100RS Motorsport.
The market for /7 bikes is broad, with an average sale price around $8,600. The wide range reflects the availability of everything from basket-case projects to perfect, low-mileage original bikes and high-dollar custom builds. Well-maintained, rideable examples represent a strong value in the vintage motorcycle world, while rare variants command top dollar.
Buying Tips
- Check for oil leaks from the pushrod tube seals, a common but simple fix. A leak from the rear main seal between the engine and transmission is a much more involved repair.
- Inspect the electrical system for signs of brittle or poorly repaired wiring, a common issue on bikes of this age. Ensure all gauges, lights, and switches function as intended.
- Verify the frame and engine numbers match for originality. The number plate is located on the steering headstock.
- Listen for a loud rattle from the front of the engine on startup, which indicates a worn timing chain.
- Test the brakes. Early models used ATE calipers that can become sticky, while later bikes switched to superior Brembo units.
Prices for BMW /7 motorcycles have ranged from $650 for projects to $47,250 for exceptional examples.
