The Ktm Sx-f 350 has a top speed of ~175 km/h (estimated; top speed is not a primary design focus for motocross bikes), produces ~63 hp and weighs 101 kg. Motoryk rates it 8.5/10.
La KTM SX-F 350 a été introduite en 2011. Elle a été développée en collaboration avec Taddy Blazusiak, pilote officiel de Red Bull KTM, et inspirée par le désir de créer une moto avec une puissance de 450 niveaux de puissance mais une maniabilité de 250 niveaux. Il est rapidement devenu emblématique lorsque Ryan Dungey a remporté le championnat de motocross AMA 450 2011 à bord de la 350, prouvant ainsi le concept dans des compétitions d'élite. Elle reste l'une des machines de motocross les plus célèbres de KTM, alliant légèreté et agilité à une puissance impressionnante dans une catégorie à part.

Ce que les acheteurs doivent savoir
Best Power-to-Weight
The 350 SX-F punches above its class with nearly 350cc power in a 250-weight chassis, giving riders a competitive edge in both 250 and 450 classes. This makes it uniquely versatile and highly sought after on the used market.
Watch Valve Intervals
The high-revving engine requires strict valve clearance checks every 15 hours of riding — neglected maintenance is the #1 cause of expensive top-end failures on used examples. Always ask for a documented service history before buying.
Strong Resale Value
KTM SX-F 350s consistently hold strong resale value due to high demand and limited used supply, often selling for 80-90% of retail within the first year. Well-maintained examples rarely sit unsold for long.

Évaluation d'un acheteur d'occasion
"The best motocrosser money can buy — if maintained religiously."
$5,500-$9,500 usedThe 350 SX-F is KTM's sweet spot machine — punchy enough to embarrass bigger bikes out of corners, light enough to flick through rhythm sections without wanting to die. That 350cc engine is genuinely clever engineering: rev it like a 250, get 450 grunt on exit. Used examples can be absolute gold or complete nightmares depending on maintenance history, so bring a magnet and check the frame welds carefully. These things get flogged hard. Maintenance costs are real. Valve checks every 30 hours, piston every 80-100 if it's been ridden properly. Ask for service receipts — if the seller looks blank, walk away. Worn linkage bearings and tired suspension are your biggest used-market headaches. Budget another $500-800 for a full refresh on a high-hour bike. The WP suspension is decent but not Showa-level plush straight off the truck. For the right rider though, nothing else does what this does. It's the thinking man's motocrosser — technically demanding but enormously rewarding once you're dialed in.
