2024 YZ125X

Incl. GST

Based on the legendary 249cc YZ liquid-cooled reed-valve-inducted two-stroke engine, the YZ250X runs a revised compression ratio, exhaust port timing, Yamaha Power Valve System timing and a model-specific CDI unit. 

To increase rider confidence in challenging cross country conditions, new smoothly integrated body panels, more narrow fuel tank design, slimmer shroud width and flatter seat all combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for better control.
