2 Stroke evolution.

The YZ125 was developed with a clear mission: to give young motocross riders a machine that can win at every level. Which is why we’ve developed our fastest ever Yamaha 125cc 2-stroke engine as well as the lightest handling high-tech chassis with industry-leading suspension and radical slimline bodywork.

Featuring lightweight race-bred engine internals and benefitting from Yamaha’s famous torque-boosting YPVS (Yamaha Power Valve System), the YZ125 develops hard-hitting power that keeps you way out front. The high-efficiency air intake ensures optimum performance and instant throttle response – and the slick shifting close-ratio 6-speed transmission helps you to shave precious seconds off your lap times.

Its sharp looking ultra slim bodywork gives you a high degree of controllability on the ground and in the air – and the flat seat and race-developed ergonomics allow you to move easily around the bike when braking and accelerating hard. The YZ125 is in it to win it – now just add your ability and prepare to enter the victorYZone!
