Bmw R 90 S
The Bmw R 90 S has a top speed of 200 km/h, produces 67 hp and weighs 215 kg. Motoryk rates it 8.5/10.
Die BMW R 90 S wurde 1973 als das Flaggschiff-Superbike von BMW vorgestellt. Sie wurde von Hans Muth mit einer markanten geräucherten Verkleidung und Doppelscheiben-Vorderradbremsen entworfen, die für die damalige Zeit revolutionär waren. Bei ihrer Markteinführung war sie das schnellste Serienmotorrad ihrer Zeit und gewann 1976 die erste AMA Superbike-Meisterschaft, gefahren von Reg Pridmore. Die R 90 S gilt weithin als das Motorrad, das den sportlichen Ruf von BMW begründete, und gilt als eines der ikonischsten Motorräder der 1970er Jahre.

Was Käufer wissen sollten
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.

"Das Motorrad, das bewies, dass BMW einen Sportster bauen kann."
Nichts vor 1973, das Tragen einer BMW-Emblem, bereitete einen auf die R 90 S vor — diese getönte Verkleidung war keine kosmetische Eitelkeit, sie funktionierte wirklich und reduzierte die Windermüdung auf langen Autobahnabfahrten auf eine Weise, mit der Konkurrenten nicht mithalten konnten. Der 898-ccm-Boxer zieht mit echter Souveränität ab 3.500 Umdrehungen pro Minute, und wenn Sie erst einmal im Sweet-Spot von 5.000-7.000 U/min sind, fühlt es sich wirklich dringend an, obwohl „dringend“ für die Verhältnisse der 1970er Jahre bedeutet, dass Sie sich grinsend nach vorne lehnen, anstatt mit den weißen Fingerknöcheln zu kneifen. Die doppelten vorderen Scheiben waren für ihre Zeit revolutionär und sorgen immer noch für Selbstvertrauen — die hintere Trommel eingeschlossen — aber der wahre Schock für alle, die einen Touring-Stau erwarten, ist, wie gut sich dieses Ding lenkt: neutral, kommunikativ, nie nervös auf einer schnellen Kehrmaschine. Die Schwachstellen sind ehrlich: Der Sitz härtet nach zwei Stunden erheblich aus, die Öltemperatur steigt im sommerlichen Stadtverkehr hartnäckig an, und die Cam-Follower werden Sie daran erinnern, dass Wartungsintervalle keine Vorschläge sind.

"Buy the best example available — compromises here cost dearly."
$18,000-$35,000 usedThe R 90 S is genuinely one of motorcycling's landmark machines — BMW's first superbike, the fastest production motorcycle of 1973, and still devastatingly handsome fifty years on. That smoked fairing and those twin Bing carbs are iconic for good reason. But buy one romantically and you'll suffer for it. These airheads demand regular valve checks every 6,000 miles, the carbs need synchronising obsessively, and finding a clean unmolested example gets harder every year as values climb. Mechanically they're surprisingly robust if maintained properly. The 898cc boxer twin pushes around 67hp — laughable now, but the torque delivery is smooth and satisfying in a way modern bikes rarely match. Shaft drive means no chain faff, which is a genuine daily pleasure. Budget serious money for a proper pre-purchase inspection from someone who knows airheads specifically. Prices have gone properly silly. You're paying museum piece money now, so only buy the best example you can find. Avoid anything with botched electrics, replaced frame sections, or carbs that have been tampered with by someone who watched a YouTube video.
