125 XC-W 2026 (MY2026)
Two-Stroke Enduro Race Tool
The Machine's Character
Strip the trail paint off and this is a race bike. The 125 cc liquid-cooled single runs throttle body injection, makes 37 hp with 16 lb-ft under it, and sits in a chromoly double-cradle frame with an aluminum subframe and forged triple clamps. WP's 48 mm closed-cartridge XACT fork and the XPLOR PDS shock give 11.8 inches of travel up front and 12.2 at the rear, both adjustable by hand. Brembo brakes, six speeds, electric start off a small lithium battery. In the small-bore enduro class this one sits at the competition end, not the easygoing trail end.
Riding it properly means standing up, reading the ground, and keeping the engine where it pulls. That is the bargain with a full-competition machine, and it ages on the same terms: built to come apart, be serviced, and go back out, so it stays sharp for as long as you keep up with it. This is for experienced off-road riders who spend their weekends in rocks, ruts, and steep technical ground and want the lightest thing that will get up them. The honest catch is a 37.8 inch seat and a 2.4 gallon tank. Neither was drawn up for casual trail days.
