KTM Press Release Below:
An unbeatable power-to-weight ratio, low maintenance costs and high-performance make the 250 XC an unrivaled machine for extremely tough cross-country terrain. The all-new 250 XC features a newly developed two-stroke engine fitted in a state-of-the-art chassis. The unrivaled performance of the lightweight 2 -stroke engine makes it a true contender against the more complex 4-strokes and is designed with the entire know-how of the KTM R&D and motorsport department. This new generation cross county weapon is faster with less vibration than any 250cc 2-stroke before.
An all-new chassis features a chromoly steel frame with high torsional rigidity with less longitudinal stiffness for excellent handling and bump absorption. Match that with a WP AER 48 air-sprung forks and new rear shock, and the 2017 KTM 250 XC is the most READY TO RACE off-road 2-stroke 250 ever created.
