Yamaha MY25 YZ125

The YZ125 represents an important evolution in Yamaha’s two-stroke lineage. Yamaha engineers put considerable thought into developing a motorcycle that would be both dominant on the racetrack and user-friendly for developing riders looking to bridge the gap between recreation riding and competitive motocross.

The advanced liquid-cooled 125cc two-stroke engine provides impressive acceleration, thrilling mid- to high-rpm power, along with supreme usability. While the lightweight finely tuned chassis means nimble handling, more control and less rider fatigue - the ideal platform for advancing skills and gaining confidence.
