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, smoothly integrated body panels, narrow fuel tank design, slim shroud width and flat seat all combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for better control.
