买家应该知道什么
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.

"这辆自行车证明了宝马可以造出一辆运动型车。"
在 1973 年之前，佩戴宝马徽章没有任何东西能让你为 R 90 S 做好准备 —— 烟熏整流罩不是表面上的虚荣心，它确实起到了作用，以竞争对手无法比拟的方式缓解了长时间高速公路行驶中的风疲劳。这位 898cc 拳击手以真正的权威从 3,500 rpm 向上拉动，一旦你进入了 5,000—7,000 rpm 的最佳转速，感觉真的很紧急，尽管按照1970年代的标准，“紧急” 意味着你是在向前倾露笑容，而不是惊慌失措。双前盘在他们那个时代是革命性的，至今仍能激发信心（包括后鼓），但对于任何期待巡回赛车的人来说，真正令人震惊的是它的操控能力：中立、善于交流，在快速扫地机上从不紧张。弱点是诚实的：座椅在两个小时后会显著变硬，夏季城市交通中油温会持续攀升，摄像头关注者会提醒你，保养间隔不是建议。

二手买家评论
"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.
