A BMW R 90 S foi introduzida em 1973 como a superbike carro-chefe da BMW, projetada por Hans Muth com uma carenagem defumada distinta e freios dianteiros de dois discos que foram revolucionários para a época. Foi a motocicleta de produção mais rápida de sua época após o lançamento, vencendo o primeiro Campeonato AMA Superbike em 1976, pilotado por Reg Pridmore. A R 90 S é amplamente considerada como a moto que estabeleceu as credenciais esportivas da BMW e é considerada uma das motocicletas mais icônicas da década de 1970.

O que os compradores devem 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.

"A moto que provou que a BMW poderia construir um sportster."
Nada antes de 1973, usar um emblema da BMW preparou você para a R 90 S — aquela carenagem defumada não era uma vaidade cosmética, ela realmente funcionava, reduzindo a fadiga do vento em longas viagens de autoestrada de uma forma que os rivais não conseguiam igualar. O boxeador de 898 cc puxa com autoridade real de 3.500 rpm para cima e, quando você está no ponto ideal de 5.000 a 7.000 rpm, parece genuinamente urgente, embora “urgente” para os padrões da década de 1970 signifique que você está se inclinando para frente sorrindo em vez de dar os dedos brancos. Os discos frontais duplos foram revolucionários para sua época e ainda inspiram confiança — incluindo o tambor traseiro —, mas o verdadeiro choque para quem espera uma aventura em turnê é o quão bem essa coisa dirige: neutra, comunicativa, nunca nervosa em uma varredora rápida. Os pontos fracos são honestos: o assento endurece consideravelmente após duas horas, a temperatura do óleo sobe teimosamente no trânsito da cidade no verão e os seguidores da câmera lembrarão que os intervalos de manutenção não são sugestões.

Avaliação do 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.
