Vehicle Information
KTM 250 SX Dirt Bike (1992-2026)
The KTM 250 SX, produced from 1992 to 2026, is a legendary 2-stroke motocross competition machine renowned for its performance and agility. Designed exclusively for racing, it consistently features a 249cc engine, focusing on a single, high-performance package rather than traditional trim levels. While specific trims are not offered, the 250 SX has undergone numerous significant engine and chassis redesigns throughout its production run. Notable generational shifts include major engine overhauls in 2000 and 2003, a comprehensive chassis and engine redesign in 2020, and a groundbreaking update in 2023. The 2023 model introduced a completely new engine with throttle body fuel injection (TBI), an electronic power-valve, a new chassis, and a 6-speed transmission, marking a significant evolution in its design and technology. These continuous developments ensure the 250 SX remains at the forefront of motocross competition. FAQ:
