2020 Yamaha YZ125X (2-Stroke)



Level up your performance. Designed to be the perfect stepping stone toward a full size cross-country machine, the all-new 2020 YZ125X is the pinnacle of lightweight, two-stroke performance on the race course.


Based on the legendary 125 cc liquid-cooled, reed-valve-inducted YZ two-stroke engine, the YZ125X utilizes a revised compression ratio, Yamaha Power Valve System (YPVS) timing, and a model-specific CDI unit, all focused on creating broad power delivery that suits off-road terrain and a wide range of rider skill levels.


An ultra-lightweight YZ125-spec frame features a carefully engineered combination of aluminum castings, forgings and extrusions for the perfect balance of rigidity and flex, with industry-leading fully adjustable, KYB speed sensitive spring-type suspension tested and tuned specifically for the needs of cross-country racers.


The 2020 YZ125X is race-ready with an aluminum tapered handlebar, YZ-F-style foot pegs, gripper seat, 18-inch rear wheel, sealed O-ring chain, off-road focused tires and suspension settings, a standard side stand and fuel tank petcock with reserve position.
