The new YZ125X racer is the perfect entry point to the world of enduro. A lightweight two-stroke that will kickstart your off-road journey and set you on a path to racing success.

Its 125cc, liquid-cooled, two-stroke, reed-valve-inducted engine sports Yamaha’s Power Valve System (YPVS), combined with a six-speed transmission tuned for smooth and controllable power character across the entire rev range. Optimised for the unique demands of racing in the bush, the Aussie version will be fitted with off-road kit as standard.



2 stroke power tuned for off road

Based on the legendary 125cc liquid-cooled, reed-valve-inducted YZ two-stroke engine, the YZ125X utilises 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.

YZ based frame

Ultra-lightweight YZ125-spec frame features carefully engineered combination of aluminium 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 enduro racers.

Cross country features

The YZ125X comes equipped with off-road focused tyres with an 18” rear wheel, larger rear sprocket, a side stand, sealed O-ring chain and a reserve fuel petcock.

Enduro-specific wheels and tyres

Cross-country-spec Dunlop Geomax AT81 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.

Industry-leading KYB fork

Industry-leading, fully adjustable KYB spring-type fork with 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.
