KTM 250 EXC (2017-Present) Specs, Performance & Photos

The engine of the 250 EXC 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 EXC 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 new well-integrated electric starter, a 6-speed Enduro transmission and a hydraulically operated DDS clutch.
