Features

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.
  • HIGH PERFORMANCE BRAKING SYSTEM: 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.
  • ADVANCED KYB® SHOCK: Revised fully adjustable KYB® rear shock features reduced-friction Kashima Coat™ internals, separate adjusters for high- and low-speed compression damping, a full lock oil rebound system for increased comfort, and 12.4 inches of travel. It all adds up to fantastic rear wheel control and class-leading capability.
  • RACE-READY TIRES: Premium Bridgestone® Battlecross X20 tires offer strong cornering grip and race-developed performance.

Engine

  • POWERFUL NEW YZ125 ENGINE: The new YZ125's two-stroke engine represents a significant 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.
  • 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.
  • CLOSE-RATIO TRANSMISSION: Revised six-speed, close-ratio transmission has wider transmission gear tooth width and new, optimized gear ratios for maximum performance.
  • DIGITAL IGNITION: Digital CDI system delivers precise spark and monitors engine speed to ensure optimal timing for faster, stronger response during hard acceleration.
  • HIGH-CAPACITY RADIATOR: Large-capacity radiator features a 10-row core with blacked-out louvers to deliver an aggressive look and maximum cooling efficiency.

Other Features

  • 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.

Top Features

  • MODERN MONSTER ENERGY® YZ STYLING: Slimmer, more aggressive bodywork including new front and rear fender design, slimmer body panels and new radiator shrouds highlight the YZ's unmatched racing pedigree. A bold new Monster Energy®‑inspired graphics package completes the factory-ride look and feel.
  • POWERFUL NEW YZ125 ENGINE: A new 125cc reed-valve-inducted two-stroke engine produces better acceleration and improved mid-to high-rpm power.
  • HIGH PERFORMANCE BRAKING SYSTEM: 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.
  • IMPROVED RIDER ERGONOMICS: A new flatter seat and more narrow fuel tank design, along with smoothly integrated body panels and slimmer shroud width, combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence.
  • REVISED SUSPENSION DAMPING: Taking the YZ125's class-defining suspension and handling characteristics to a new level, front and rear suspension has been revised to further improve bump absorption and cornering performance. KYB® inverted front fork now includes a leaf spring in the mid-speed valve for increased performance and comfort.
  • IMPROVED FUELING: High-precision Hitachi Astemo® Keihin PWK38S carburetor features a power jet, throttle position sensor and 3D-map-controlled CDI unit for precise ignition timing. The result is clean, crisp throttle response, superior rideability and excellent over-rev character.
  • AIR INTAKE DESIGN: Updated intake design allows for a straighter, more efficient draw of air into the intake tract.
  • 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.
  • PERFECT FOR ASPIRING MOTOCROSSERS: A pure motocross machine, the light, nimble, competition-ready YZ125 is the perfect choice for riders stepping up from the 85cc class.
