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.

2017 250XC Highlights

  • NEW 249cc engine features an all new architecture with a new shaft arrangement for better mass centralization.
  • NEW cylinder with twin-valve controlled power valve for smooth power that can be adjusted within seconds for different track conditions.
  • NEW lateral counter balancer reduces engine vibrations for less rider fatigue at the end of the race.
  • NEW reworked 6-speed transmission shifts easier with more precision.
  • Hydraulically operated DDS clutch features a damping system for better traction and durability.
  • NEW 38mm Mikuni TX carburetor for smoother and more controllable power delivery. It is also less sensitive to altitude and temperature changes.
  • NEW lightweight Chromoly steel frame provides high torsional rigidity with less longitudinal stiffness resulting in excellent handling and energy absorption.
  • NEW Tuned exhaust pipe for maximum power output.
  • NEW WP AER 48 front fork with a sophisticated air spring design and separate damping for easy adjustment to any track condition, rider weight or skill level is tuned specifically for off-road competition. The fork is now 3.1 pounds lighter than the 4CS unit it replaces.
