Six-speed, close-ratio transmission optimizes gear ratios for maximum performance.
Digital CDI ignition system delivers precise spark and monitors engine speed to ensure optimal timing for faster, stronger response during hard acceleration.
Large-capacity radiator features a 10-row core with four louvers to deliver maximum cooling efficiency at all performance levels.
Primary kickstarting ensures easy restarts in any gear.
Trick, works-style clutch lever features race-spec barrel adjuster for on-the-fly adjustability.
Chassis/Suspension:
A carefully engineered, advanced aluminum frame and swingarm give the YZ125 the best handling in the class.
Speed-Sensitive System 48mm Kayaba fork tubes move the transfer control valves (TCV) above the fork springs, so that damping force is controlled by piston speed instead of position. Along with a bigger base valve hole, the result is a smooth ride and super-precise handling.
Removable aluminum rear subframe constructed of square-section tubing for reduced weight.
Rear, fully adjustable Kayaba shock features a super-light titanium shock spring and reduced-friction Kashima coating of internals. 12.4 inches of travel, separate adjusters for high- and low-speed compression damping, and a full lock oil rebound system for increased comfort all add up to fantastic rear wheel control and a sweet ride.
Lightweight front and rear calipers with aluminum pistons and anti-bubble front master cylinder, 250mm floating front and 245mm rear discs, deliver strong stopping power with progressive feel.
Tapered rear wheel spacers ease sliding the rear wheel into place for quicker tire changes.
Premium Dunlop knobbies offer race-spec traction and wear.
Additional Features:
Special-design “gripper” type seat and fuel tank, forward-canted steering crown and low ProTaper handlebar all help create greater freedom of movement and more comfortable ergonomics for riders.
Wide, cleated, folding titanium footpegs are lightweight and provide excellent comfort, grip and ground clearance.
Use of light, box-head bolts throughout the chassis eases maintenance while reducing weight for increased performance.
