Ra POWERFUL NEW ENGINE

The new YZ125's two-stroke engine represents an increase in power and usability over the 2021 model. Nearly every functional part of the engine is new—from the cylinder body, cylinder head, piston, piston pin, connecting rod, crankcase and expansion chamber, to a revised cylinder port shape and updated cylinder port timing. It's a change that is immediately apparent at the first crack of the throttle and throughout the entire rpm range.

 

Ra LIGHTWEIGHT FRAME

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. Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.

Cross country focused suspension setup and Dunlop® Geomax AT81 tires, 18-inch rear wheel, wide ratio transmission, narrow expansion chamber, sealed O-ring chain, a standard side stand and fuel tank petcock with reserve position are perfect for XC racing.

NEW, MODERN MONSTER ENERGY® YZ STYLING Ra

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.
