1975 BMW R90S for Sale

1975 BMW R90S R Rear

Earlier this week, we featured a very nice R100/7 with a bit of café style that made it look like the earlier R90S, racier sibling of the more conservative “Slashy” bikes. My new term for the R60/2, R75/5, etc bikes. Just made it up: feel free to use it.

The wonderful thing about old BMW’s is that their handling and competence is all out of proportion to the on-paper specs and unlikelyness of the powertrain combo. You’d expect them to be pretty slow and clunky, but, as Pirelli likes to tell us: “power is nothing without control.”

Japanese bikes of the period routinely blew their European opposition into the weeds in terms of outright power, yet somehow folks kept buying and riding the European marques so often featured on this page. Probably because they lived long enough to buy new ones and all those young hotheads on their Kawasaki H1’s died at the first serious corner they came to.

And considering how uncomfortable and uncompromising the Latin racers of the period were, it’s hard to imagine you could have speed, handling, and comfort in one package: introduced in 1974, the R90S placed first and second at the very first AMA Superbike race ever held.

Always happy to embrace unusual solutions, BMW mounted the R90S’ front brake master cylinder below the fuel tank and connected it to the lever via a short cable, preventing damage in the event of a crash.

It’s no garage queen, but this seems like a pretty nice example of a very collectable Bavarian bike, the choice of an intellectual rebel with a cause. I’d ditch those ridiculous “CYCLONE” stickers as soon as I could, but otherwise, this looks to be the perfect classic useable classic, combining “sport” and “touring” in equal measures.

    A very nice bike and great fun to ride hard but those front brakes are no fun. Cable/hydraulic are the worst of both worlds and are a colossal pain toLater Brembos are waayyy better and actually stop you.
