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.
La KTM 990 Supermoto a été introduite en 2008 en tant que variante de supermoto homologuée pour la route de la plateforme 990 Super Duke/Adventure axée sur l'aventure, partageant son moteur bicylindre en V LC8. Il a été conçu pour apporter un style et une maniabilité de supermoto agressifs à une machine de plus grande cylindrée, comblant ainsi le fossé entre les supermotos purement axées sur la piste et les motos de performance destinées à la route. La production s'est poursuivie jusque vers 2013, lorsque KTM s'est concentrée sur les nouvelles gammes Duke et Adventure, faisant de la 990 SM une machine relativement rare et recherchée par les passionnés de supermoto.

Ce que les acheteurs doivent savoir
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.

"Une folie de supermotard dotée d'une véritable capacité à manger sur la route."
Le SM 990 reprend l'impressionnant bicylindre LC8 du Super Duke et l'enveloppe dans des proportions dignes d'un supermotard : sa hauteur de selle de 900 mm et ses roues de 17 pouces lui donnent l'impression d'être une arme tranchante comme un rasoir dès que vous basculez dans un virage. Le couple atteint un pic autour de 4 500 tr/min et vous fait avancer de 7 000 tr/min, et sur une route B étroite, il humiliera les motos de sport qui ont l'air plus rapides sur le papier. Mais vivre avec, c'est une autre histoire : la gestion de la chaleur est brutale dans les embouteillages, le siège est un dispositif de punition au bout de deux heures, et les premiers calculateurs provoquaient des problèmes de ravitaillement occasionnels que KTM a résolus discrètement à mi-production. Ce n'est pas un vélo de randonnée, il n'essaie pas de l'être, mais rien d'autre ne soulage cette démangeaison particulière.

Évaluation d'un acheteur d'occasion
"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.
