LEVEL UP YOUR PERFORMANCE

Designed to be the perfect step up to a full size X-country machine, this light weight 2-stroke is the pinnacle of performance on the race course.

Features may include:

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.

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.

ADDITIONAL

  • Cross-Country Ergonomics

A racy "gripper" type seat and narrow fuel tank combine with a tapered aluminum handlebar and adjustable mounts to create greater freedom of movement and more comfortable ergonomics for riders.

  • Cross-Country Features

The YZ125X comes equipped with off-road focused tires with an 18” rear wheel, larger rear sprocket, a side stand, sealed O-ring chain and a reserve fuel petcock.
