2026 Yamaha YZ125XTWO-STROKE TRAILBLAZER The YZ125X sets the standard for light, fast two-stroke fun! The perfect entry into the world of XC and enduro competition. Features may include: Premium Wheels & Tires Slick blue Excel® rims provide exceptional durability and a premium look. They come wrapped in high performance Dunlop® Geomax MX33 tires offering race-developed performance for a wide range of terrain. Cross Country Features The YZ125X is built for competition with an 18-inch rear wheel, enduro-focused suspension setup, larger rear sprocket, side stand, sealed O-ring chain and reserve fuel petcock, all adding up to exceptional cross country performance. Two-Stroke Power: Tuned for Enduro The YZ125X's advanced, liquid-cooled 125cc two-stroke engine utilizes a revised compression ratio, revised YPVS timing and a model-specific digital CDI unit compared to its motocross sibling—all focused on creating a broad, usable power delivery specifically suited to cross country and enduro-style competition. Lightweight Aluminum Frame The lightweight, race-proven YZ125-spec aluminum semi-double cradle frame is engineered to provide the perfect balance of rigidity and flex for competition-ready handling character and composure. Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
