The new 250 SX features a highly developed two-stroke engine fitted in a state-of-the-art chassis. Designed with the entire know-how of the KTM R&D and motorsport department the latest generation SX with its class-leading performance is faster with less vibration than any 250cc two-stroke before. The unrivalled performance of the lightweight 2-stroke engine makes it a true contender against the more complex 4-strokes. Its chassis features a chromoly steel frame with high torsional rigidity with less longitudinal stiffness for excellent handling and bump absorption. Matched with updated WP AER 48 air-sprung forks and rear shock, new radiator guards and revised carburetor, the 2018 KTM 250 SX is the most READY TO RACE 2-stroke ever created. This masterpiece of KTM’s R&D and motorsport departments is born to lead the next pack of winners that prefer premix.
