2015 KTM 250XCW Dirt Bike Torque Specs
Shop parts for a 2015 KTM 250XCW Dirt Bike.
The 2015 KTM 250XCW continued to refine the cross-country wide formula with updates to the cylinder and power valve that sharpened throttle response in the low-to-mid RPM range — precisely where cross-country racing is won and lost in tight technical sections. The wide-ratio gearbox remained a standout feature, keeping the engine in its powerband across the widest possible range of cross-country terrain. Proper torque specification on all key fasteners is essential for reliability over a full season of demanding race conditions.
