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.
  • RIDER-FRIENDLY CHASSIS: Lightweight finely tuned chassis means nimble handling, more control and less rider fatigue—the ideal platform for advancing skills and gaining confidence.
  • 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: 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.
  • HIGH PERFORMANCE BRAKING SYSTEM: The high performance braking system features a 270mm front rotor, 240mm rear rotor, large front pistons and rigid calipers, all combining to provide exceptional braking power and feel.
  • CONFIDENCE-INSPIRING ERGONOMICS: A carefully considered ergonomic design includes a flatter seat, narrow fuel tank, smoothly integrated body panels and slim shroud width to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence.
  • RACE-READY TIRES: Premium Bridgestone® Battlecross X20 tires offer strong cornering grip and race-developed performance.

  • PRECISE FUELING & IGNITION TIMING: 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.
  • CLOSE-RATIO TRANSMISSION: Close-ratio six-speed transmission has wider transmission gear tooth width and 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: High-capacity radiator with dark louvers deliver maximum cooling efficiency and an aggressive look.

Other Features

  • RACE-READY FEATURES: Complete with an aluminum handlebar, two-position adjustable handlebar clamp, wide footpegs, gripper seat, adjustable clutch lever with works-style cable adjuster and lightweight rear sprocket design, the YZ125 is competition-ready straight out of the crate.
