The 2026 KTM 350 SX-F continues to dominate the "perfect middle ground" in motocross, balancing 250-class agility with 450-class power. At its heart lies a high-revving 349.7 cc, 4-stroke engine featuring a 95 mm bore and 63.4 mm stroke, designed to deliver a broad, usable powerband. This lightweight powerhouse is paired with a precise DDS multi-disc wet clutch and Brembo hydraulics, ensuring consistent feel and fade-free performance during intense motos. Starting is effortless thanks to a dedicated electric starter, while the 5/8 x 1/4" chain drive efficiently transfers power to the dirt.
The chassis is engineered for aggressive handling and maximum clearance, featuring a 950 mm seat height and a substantial 375 mm of ground clearance to navigate deep ruts and heavy landings. Despite its robust performance, the bike remains remarkably lean with a dry weight of just 99.5 kg, making it one of the most flickable machines in its category.
