2018 Yamaha YZ250X (2-Stroke)


Cross country and enduro racing are currently experiencing increased popularity and growth. Based on the legendary YZ250 2-stroke, the "X" version has been developed using all of Yamaha's extensive 2-stroke knowledge to produce a model that offers a high level of performance for cross country racing. The YZ250X is a lightweight, compact machine that is both exciting to ride and affordable to own and maintain.

Features may include:


The YZ250X is a super light weight package that offers serious 2-stroke power. The engineers modified the cylinder head, adjusted the compression ratio, revised the exhaust port timing and changed the gear ratios in the 5-speed transmission to better suit cross country racing (vs. YZ250). The YZ250X engine offers a good depth of power with an easy to use engine character.


Cross country focused chassis features include softer suspension settings front & rear, an 18" rear wheel for more puncture resistance, an aluminum side stand and a fuel petcock that offers a reserve position for peace of mind (vs. YZ250).
