Segment: Enduro/Offroad
Production started year: 2017
The engine of the 250 SX has been known and respected for being the most powerful 2-stroke engine in its class. But we thought the segment could use an extra push and a solid statement: 2-strokes have a future at KTM. Their outstanding power-to-weight ratio, low cost and simplicity see to that. Putting our money where our mouth is, we gave the 250 SX engine an all new architecture with a new shaft arrangement for better mass centralization, a new cylinder with twin-valve controlled power valve, a new counter balance shaft for less engine vibrations, a 5-speed transmission and a hydraulically operated DDS clutch.
