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 ERGONOMICS
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.

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.
