Yamaha YZ125X Features

Industry-Leading KYB® Fork The industry-leading, fully adjustable KYB® spring-type fork with speed-sensitive damping uses piston speed to control the pressure for super-precise handling and a smooth ride. With minimal wasted stroke or abrupt shocks for the rider, this bike is tuned for cross-country racing needs.
Smooth KYB® Shock Fully adjustable KYB® rear shock features 12.4 inches of travel, separate adjusters for high- and low-speed compression damping, and a full lock oil rebound system for increased comfort, control, and fantastic rear-wheel traction in challenging conditions.
YZ-Based Frame A carefully engineered aluminum frame and swingarm give the Yamaha YZ125X the famous handling proven by the championship-winning YZ motocross riders on tracks worldwide.
Lightweight Subframe Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
270mm Front Brake A large 270mm front rotor coupled with high-performance pad material offers outstanding machine control and performance with exceptional stopping power and controllability.
