Shop parts for a 2014 KTM 250XCW Dirt Bike.
The 2014 KTM 250XCW represented a significant update for KTM’s flagship two-stroke cross-country wide machine. For 2014 KTM introduced revised engine internals for improved low-to-mid power delivery, a new frame geometry targeting improved rider ergonomics, and updated WP suspension calibrated specifically for endurance cross-country competition. The “wide” designation refers to the wider-ratio six-speed gearbox that makes the 250XCW an even better fit for multi-terrain riding than the standard XCW.
Engine Torque Specifications
The 2014 249cc liquid-cooled two-stroke engine uses KTM’s PECS (Power-controlled Exhaust System) power valve for broad torque spread. Critical torque values on this engine include the cylinder head studs and the power valve housing, both of which must be torqued in sequence to avoid distortion.
