A race-proven, highly developed aluminium semi-double cradle frame is engineered to provide the perfect balance of rigidity and flex for competition-ready handling character and composure. Removable aluminium rear subframe is constructed of square-section tubing for reduced weight. 

The YZ125X comes equipped with an 18-inch rear wheel, standard side stand, sealed O-ring chain, reserve fuel petcock, lightweight bar pad, headlight and scraper between the fork’s dust and oil seal, all adding up to exceptional off-road performance.

A racy ‘gripper’ type seat and narrow fuel tank combine with a tapered aluminium handlebar and adjustable mounts to create greater freedom of movement and more comfortable ergonomics for riders.

Industry-leading, fully adjustable KYB spring-type forks now feature tool-free compression adjustment at the top of each fork leg. The speed sensitive damping uses piston speed to control damping force for super-precise handling and a smooth ride, with minimal wasted stroke or abrupt shocks for the rider – all tuned for the demands of off-road racing.

Cross-country-spec Dunlop Geomax MX33 tyres front and rear are ready to head straight to the races. An 18-inch rear tyre has a taller sidewall to improve comfort and reduce pinch flats.

The YZ125’s advanced, liquid-cooled YPVS-equipped 125cc two-stroke engine provides impressive acceleration, thrilling mid- to high-rpm power, along with supreme usability.
