FEATURES & BENEFITS

ENGINE

GNCC®-Tuned YZ125 Power
Based on the legendary 125cc liquid-cooled, reed-valve-inducted YZ two-stroke engine, the YZ125X utilizes a revised compression ratio, Yamaha Power Valve System (YPVS) timing, and a model-specific CDI unit—all focused on creating broad power delivery that suits off-road terrain and a wide range of rider skill levels.

Revised Power Valve
The YZ125X features the patented Yamaha Power Valve System—with broader opening timing compared to the motocross version for smoother power—to create a smooth balance of power across the rev range.

Narrow Exhaust Pipe
The compact exhaust expansion chamber provides both horizontal and vertical clearance on tight, technical trails, while still providing
excellent exhaust efficiency.

Racing Intake System
Specially designed carbon fiber reed-valve petals improve throttle response and engine performance across the entire rpm range.

Six-Speed Transmission
Smooth-shifting six-speed transmission ensures proper gearing from tight woods sections to wide-open fire roads maximizing the power delivery form the two-stroke powerplant.

YZ125 Cooling System
Large-capacity radiator features a large cooling core with protective louvers for maximum cooling efficiency and durability in racing conditions.

Digital Ignition
Digital CDI ignition system delivers precise spark for faster, stronger response anywhere in the powerband, specifically tuned for the needs of the YZ125X.

CHASSIS/SUSPENSION

Industry-Leading KYB® Fork
Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping uses piston speed to control damping force for super-precise handling and a smooth ride, with minimal wasted stroke or abrupt shocks for the rider—all tuned for the demands of cross country racing.

Smooth KYB® Shock
Rear, fully adjustable KYB® 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 off-road conditions.

YZ-Based Frame
A carefully engineered aluminum frame and swingarm give the YZ125X the famous handling proven by the championship winning YZ motocrosser on tracks around the world.

Lightweight Subframe
Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.

270mm Front Brake
Large 270mm front disc brake coupled with high-performance pad material offers outstanding machine control and performance, with exceptional stopping power and controllability.

Enduro-Specific Wheels and Tires
Cross country-spec Dunlop® Geomax® AT81 tires front and rear are ready to head straight to the races. An 18-inch rear tire has a taller sidewall to improve comfort and reduce pinch flats.
