2021 Yamaha YZ125

The perfect step up to a full-size Cross Country machine, this lightweight 2-stroke is the pinnacle of performance on the race course.

Features may include:

• 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.

• Industry-Leading KYB® Fork

The industry-leading, fully adjustable KYB® spring-type fork with speed-sensitive damping uses piston speed to control the damping force for super-precise handling and a smooth ride. With minimal wasted stroke or abrupt shocks for the rider, this bike is 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 thats proven by the championship-winning YZ motocrosser on tracks around the world.

• Cross Country Ergonomics

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

• Cross Country Features

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