2 Stroke evolution.

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!

Yamaha has been building 2-stroke motocross bikes for the past 50 years – and has been an equally long history in racing. It is this unrivalled experience that has enabled the company to develop the latest YZ125 – a bike that is built to take you into the victorYZone!
