KTM 990スーパーモトは、LC8 Vツインエンジンを搭載したアドベンチャー志向の990スーパーデューク/アドベンチャープラットフォームのストリートリーガルスーパーモトバリアントとして2008年に発売されました。このエンジンは、大排気量のマシンにアグレッシブなスーパーモトスタイルとハンドリングをもたらすように設計され、純粋にトラックに焦点を当てたスーパーモトと公道を走るパフォーマンスバイクとのギャップを埋めるように設計されています。生産は2013年頃まで続き、KTMの焦点は新しいデュークとアドベンチャーのラインナップに移り、990 SMはスーパーモト愛好家の間では比較的希少で人気のあるマシンになりました。

購入者が知っておくべきこと
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.
年別の世代と仕様
最初の発売は、990スーパーデュークプラットフォーム、75度LC8 Vツイン、WPサスペンション、ブレンボブレーキをベースにしています。
"本物のロードイーティング機能を搭載したスーパーモト・マッドネス。"
SM 990は、Super Dukeの強烈なLC8ツインを採用し、スーパーモトらしいプロポーションを実現しています。900mmのシート高と17インチのホイールにより、コーナーに転倒した瞬間、カミソリのように鋭い武器のように感じられます。トルクは4,500 rpm前後で強く当たり、7,000回転で確実に前進します。タイトなBロードでは、紙の上ではより速く見えるスポーツバイクに屈辱を与えるでしょう。しかし、この状態での生活はまた別の話です。交通中では熱管理は厳しく、シートは2時間経過すると罰装置になり、初期のECUでは時折燃料供給の問題が発生し、KTMは生産の途中で静かに対処しました。これはツーリングバイクではなく、そうなることを目指しているわけでもありませんが、この特定のかゆみを掻き立てるものは他にありません。

中古購入者レビュー
"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.
