2025 Yamaha YZ125X – Two-Stroke Enduro & Cross Country Dirt Bike
The 2025 Yamaha YZ125X is built for riders who demand lightweight agility, explosive two-stroke power, and competition-ready performance. Designed specifically for enduro, GNCC®, and cross country racing, the YZ125X combines Yamaha’s legendary durability with cutting-edge racing technology.
At its core is a 125cc liquid-cooled, 2-stroke engine with the Yamaha Power Valve System (YPVS™), tuned with a model-specific CDI unit and revised compression ratio for crisp throttle response, strong mid-to-top power, and unmatched rideability. A close-ratio 6-speed transmission, Hitachi Astemo® Keihin PWK38S carburetor, and high-capacity radiator ensure consistent performance in the toughest racing conditions.
The ultra-lightweight aluminum semi-double cradle frame delivers precise handling and durability, while the KYB® Speed-Sensitive System 48mm fork (now featuring tool-less compression adjusters) and fully adjustable KYB® rear shock with Kashima Coat™ provide 11.8" and 12.4" of travel for industry-leading suspension. Premium Excel® wheels wrapped in Dunlop® Geomax MX33 tires, hydraulic disc brakes (270mm front, 240mm rear), and a slim ergonomic design make the YZ125X a true race weapon.
Additional GNCC®-ready features include an 18-inch rear wheel, sealed O-ring chain, side stand, reserve fuel petcock, and aggressive YZ family styling with embedded graphics for lasting durability.
Whether you’re chasing the podium or pushing your limits on the trails, the 2025 Yamaha YZ125X is engineered to dominate.
