La BMW R 90 S a été présentée en 1973 en tant que superbike phare de BMW, conçue par Hans Muth avec un carénage fumé distinctif et des freins avant à double disque révolutionnaires pour l'époque. C'était la moto de série la plus rapide de son époque à sa sortie, remportant le premier championnat AMA Superbike en 1976, piloté par Reg Pridmore. La R 90 S est largement considérée comme la moto qui a établi la réputation sportive de BMW et est considérée comme l'une des motos les plus emblématiques des années 1970.

Ce que les acheteurs doivent savoir
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.

"La moto qui a prouvé que BMW pouvait construire un sportster."
Avant 1973, le port d'un insigne BMW ne vous préparait à la R 90 S : ce carénage fumé n'était pas une vanité esthétique, il fonctionnait vraiment, réduisant la fatigue due au vent sur les longs trajets en autoroute d'une manière inégalée par vos concurrents. Le boxer de 898 cm3 tire avec une réelle autorité à partir de 3 500 tr/min, et une fois que vous êtes dans la zone idéale de 5 000 à 7 000 tr/min, cela semble vraiment urgent, même si « urgent » selon les normes des années 1970 signifie que vous vous penchez vers l'avant en souriant plutôt que de vous lancer à coups de poing. Les deux disques avant étaient révolutionnaires pour leur époque et inspirent toujours confiance, y compris le tambour arrière, mais le véritable choc pour tous ceux qui s'attendent à une poussette de tourisme, c'est de constater à quel point cet appareil tient bien la route : neutre, communicatif, jamais nerveux sur une balayeuse rapide. Les points faibles sont honnêtes : le siège durcit considérablement au bout de deux heures, la température de l'huile augmente obstinément dans la circulation urbaine estivale et les caméras vous rappelleront que les intervalles d'entretien ne sont pas des suggestions.

Évaluation d'un acheteur d'occasion
"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.
