There is no better proof of the 250 SX-F's supremacy than three consecutive MX2 world championship titles. But that’s no reason for KTM to rest on its laurels. The new model is now available with a revamped chassis and an electric starter that proves its worth in many situations. Hence the smallest four-stroke in the KTM MX range continues to guarantee top places.
