2026 125cc Lightweight 2-Stroke

The culmination of more than 50 years of Yamaha two-stroke innovation, the latest YZ125 is a bike built to take you to the VictorYZone.

Along with its advanced aluminium frame, class-leading KYB® suspension and ultra slim bodywork providing a high degree of controllability both on the ground and in the air, it’s designed for competition straight out of the box.
