Slimmer, more aggressive bodywork including new front and rear fender design, slimmer body panels and new radiator shrouds highlight the YZ's unmatched racing pedigree. A bold new Monster Energy®‑inspired graphics package completes the factory-ride look and feel.
A new 125cc reed-valve-inducted two-stroke engine produces better acceleration and improved mid-to high-rpm power.
Lightweight braking system features larger front pistons, a more rigid caliper, a redesigned 270mm front rotor with a 30% increase in pad contact area and higher friction pad material, all combining to provide exceptional braking power and feel. The redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, further reducing unsprung weight with no compromise on performance.
A new flatter seat and more narrow fuel tank design, along with smoothly integrated body panels and slimmer shroud width, combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence.
Taking the YZ125's class-defining suspension and handling characteristics to a new level, front and rear suspension has been revised to further improve bump absorption and cornering performance. KYB® inverted front fork now includes a leaf spring in the mid-speed valve for increased performance and comfort.
High-precision Hitachi Astemo® Keihin PWK38S carburetor features a power jet, throttle position sensor and 3D-map-controlled CDI unit for precise ignition timing. The result is clean, crisp throttle response, superior rideability and excellent over-rev character.
Updated intake design allows for a straighter, more efficient draw of air into the intake tract.
Race-proven, highly developed aluminum semi-double cradle frame is engineered to provide just the right amount of strength and flex for the perfect balance of stability and cornering performance.
A pure motocross machine, the light, nimble, competition-ready YZ125 is the perfect choice for riders stepping up from the 85cc class.
