Agility. Ability. Victory.

Nothing compares to the YZ125 experience. With its explosive 2-stroke engine power, super-light aluminium chassis and outstanding agility, the YZ125 accelerates, turns and brakes like nothing else. Its industry-leading speed sensitive forks give you precision steering for faster cornering – and the Monocross rear end soaks up the bumps to ride with ease.

The compact body enables you to rapidly shift your body weight and throw the YZ around at will – and its razor sharp styling and coordinated blue wheels show off its factory racer DNA. Discover the ultimate lightweight 2-stroke. And aim for the top.
