Features may include:

ENGINE

• Powerful New YZ125 Engine

The new YZ125's two-stroke engine represents an increase in power and usability over the 2021 model. Nearly every functional part of the engine is new—from the cylinder body, cylinder head, piston, piston pin, connecting rod, crankcase and expansion chamber, to a revised cylinder port shape and updated cylinder port timing. It's a change that is immediately apparent at the first crack of the throttle and throughout the entire rpm range.

• New Air Intake Design

Updated intake design allows for a straighter, more efficient draw of air into the intake tract.

• Yamaha Power Valve System

Patented YPVS™ combines crisp, hard-hitting bottom-end acceleration with strong mid-range and top-end.

CHASSIS/SUSPENSION

• Lightweight Frame

Race-proven, highly developed aluminum semi-double cradle frame is engineered to provide just the right amount of strength and flex for the perfect balance of stability and cornering performance. Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.

• New Brake System

An updated lightweight braking system features larger front pistons, a more rigid caliper, a redesigned 270mm front rotor with a 30% increase in pad contact area and higher friction pad material, all combining to provide exceptional braking power and feel. The redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, further reducing unsprung weight with no compromise on performance.

• Industry-Leading KYB® Fork

The Speed-Sensitive System 48mm inverted KYB® fork includes a leaf spring in the mid-speed valve for more precise damping and increased performance and comfort, while offering up 11.8 inches of travel.

ADDITIONAL

• Race-Ready Features

Complete with an aluminum handlebar, two-position adjustable handlebar clamp, wide foot pegs, gripper seat, adjustable clutch lever with works-style cable adjuster and a new lightweight rear sprocket design, the YZ125 is competition-ready straight out of the crate.
