Ktm Sm 990
The Ktm Sm 990 has a top speed of 220 km/h (estimated; note: limited real-world data available), produces 113 hp and weighs 198 kg. Motoryk rates it 8.2/10.
KTM 990 Supermoto 于 2008 年推出，是面向冒险的 990 Super Duke/Adventure 平台的街头合法超级摩托车变体，共享其 LC8 V-twin 发动机。它旨在为大排量机器带来激进的超级摩托车造型和操控性，弥合纯粹以赛道为重点的超级摩托车和公路性能自行车之间的差距。生产一直持续到2013年左右，当时KTM的重点转移到了更新的杜克和冒险系列上，这使得990 SM成为超级摩托车爱好者中相对罕见且备受追捧的机器。

买家应该知道什么
LC8 Engine Quirks
The 75-degree V-twin LC8 engine is powerful but known for running hot in slow traffic, often causing discomfort for the rider. Ensure the cooling system and thermostat are in good condition before buying.
Watch the Valve Intervals
Valve clearance checks are required every 6,000 miles and are labor-intensive, making them expensive at a dealership. Always ask for service history to confirm these were not skipped by a previous owner.
Strong Resale Value
The SM 990 holds its value well due to its cult following and limited production numbers, making it a smart buy if purchased at the right price. Low-mileage, well-maintained examples are particularly sought after.
按年份划分的世代和规格
首次发布基于 990 Super Duke 平台、75 度 LC8 V 型双缸、WP 悬架、布雷博制动器。
"疯狂的超级摩托车，具有真正的越野能力。"
SM 990 采用了 Super Duke 重磅的 LC8 双胞胎，并以恰当的超级摩托车比例包裹了——900mm 的座椅高度和 17 英寸的车轮让它在你翻入弯道的那一刻感觉就像一把锋利的武器。扭矩在 4,500 rpm 左右猛击，绝对能将你向前推进 7,000，而在狭窄的 B 路上，它会羞辱那些在纸面上看起来更快的运动自行车。但是，忍受这种情况则是另一回事：交通中的热管理非常残酷，座椅是过去两个小时的惩罚手段，早期的ECU偶尔会引发一些小问题，KTM在制作中期悄悄地解决了这些问题。它不是一辆旅行车，也不是想成为一辆旅行车，但没有其他东西能引起这种特别的瘙痒。

二手买家评论
"A brilliant, high-maintenance lunatic that rewards prepared, attentive owners."
$6,500-$10,500 usedThe SM 990 is the supermoto that rewired my brain about what a big single-cylinder machine could do. That LC8 V-twin pulls hard from nothing and screams past 9,000rpm like it's personally offended by speed limits. It's genuinely fast, absurdly flickable, and sounds absolutely mental. When it's working, nothing touches it for urban aggression or canyon-carving entertainment. Here's the honest part nobody tells you: these bikes eat money when neglected. Check the valve clearances obsessively — they go out of spec and previous owners routinely ignore it. The throttle bodies need syncing, the subframes crack, and KTM's orange paint chips if you breathe near it. Always pull the maintenance history and budget $500-800 immediately for a proper service regardless. Buy one that's been genuinely maintained, not just washed before sale. Find a bike from an enthusiast rather than someone who bought it impulsively and discovered 900cc supermoto wasn't their personality after all. They're out there, and when you find the right one, it's one of the most rewarding bikes you'll ever own.
