Tras su lanzamiento, fue la motocicleta de producción más rápida de su época, y ganó el campeonato inaugural de Superbike de la AMA en 1976 con Reg Pridmore.

Lo que los compradores deben saber
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 que demostró que BMW podía construir una Sportster."
Antes de 1973, llevar un emblema de BMW no te preparaba para la R 90 S: ese carenado ahumado no era una vanidad estética, realmente funcionaba, ya que reducía la fatiga provocada por el viento en largas temporadas en las autopistas de una manera que los rivales no podían igualar. El bóxer de 898 cc tira con verdadera autoridad a partir de las 3500 rpm y, una vez que estás en el punto óptimo de 5000 a 7000 rpm, se siente realmente urgente, aunque «urgente» según los estándares de la década de 1970 significa que te inclinas hacia adelante con una sonrisa en lugar de con los nudillos blancos. Los discos frontales duales supusieron una revolución para su época y siguen inspirando confianza (incluido el tambor trasero), pero el verdadero asombro para cualquiera que espere una gira a toda velocidad es lo bien que conduce: neutral, comunicativo y nunca nervioso en una barredora rápida. Los puntos débiles son honestos: el asiento se endurece considerablemente después de dos horas, la temperatura del aceite sube de forma persistente en el tráfico urbano en verano y los seguidores de cámara le recordarán que los intervalos de servicio no son una sugerencia.

Reseña de un comprador usado
"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.
