Bmw R 90 S
The BMW R 90 S was introduced in 1973 as BMW's flagship superbike, designed by Hans Muth with a distinctive smoked fairing and twin-disc front brakes that were revolutionary for the era. It was the fastest production motorcycle of its time upon release, winning the inaugural AMA Superbike Championship in 1976 ridden by Reg Pridmore. The R 90 S is widely regarded as the bike that established BMW's sporting credentials and is considered one of the most iconic motorcycles of the 1970s.

What Buyers Should Know
Strong Collector Value
The R 90 S was the world's fastest production motorcycle when launched in 1973, and its status as BMW's first superbike makes it highly sought after by collectors. Well-preserved examples regularly fetch $15,000–$30,000+ at auction.
Watch the Airhead Electrics
The aging electrical system, particularly the Bosch components and wiring harness, is prone to gremlins on bikes that haven't been properly maintained. Always verify the charging system and inspect for amateur rewiring before buying.
Iconic Dual-Disc Brakes
The R 90 S was among the first production motorcycles to feature dual front disc brakes, a groundbreaking feature for its era. However, the original Ate calipers can seize after decades of use, so a brake service is essential on any purchase.
