購入者が知っておくべきこと
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.

"BMWがスポーツスターを作れることを証明したバイク。"
1973年以前は、BMWのバッジを身に着けていても、R 90 Sへの準備は何もありませんでした。スモークフェアリングは見た目の虚栄心ではなく、本当に機能し、ライバルにはない方法で長いアウトバーンスティントでの風による疲労を軽減しました。898ccのボクサーは、3,500rpmから力強く引っ張り、5,000~7,000rpmのスイートスポットに入ると、本当に切迫感があります。ただし、1970年代の基準では「緊急」とは、ホワイトナックルではなく前かがみになってニヤリと笑っていることを意味します。デュアルフロントディスクは、その時代にしては革命的であり、リアドラムも含めて自信を掻き立てます。しかし、ツーリングプラダーを期待している人にとっての本当の衝撃は、これがどれほどうまく操縦できるかということです。ニュートラルで、コミュニケーションが取れ、速いスイーパーでも緊張することはありません。弱点は正直なところです。2時間後にシートがかなり硬くなり、夏の都市交通ではオイル温度が頑固に上昇し、カムフォロワーはサービス間隔は提案ではないことを教えてくれます。

"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.
