2011 Yamaha YZ125

(discontinued)

Engine:

• Reed-valve spacer improves acceleration across the entire powerband.
• Amazingly compact 124cc reed-valve-inducted two-stroke helps produce an awesome power-to-weight ratio.
• Patented YPVS® power-valve system combines crisp, hard-hitting bottom-end acceleration with strong midrange and eye-opening top-end.
• 38mm Mikuni® TMX carburetor gives excellent throttle response and serious horsepower.
• 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:

• YZ250F-style front-brake caliper and wave-style front and rear discs minimize unsprung weight and provide excellent stopping power.
• A carefully engineered, advanced aluminum frame and swingarm give the YZ125 the best handling in its class.
• Speed-Sensitive System 48mm KYB® fork; damping force is controlled by piston speed which provides a smoother, more precise ride.
• Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
• Rear, fully adjustable KYB® 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.
• 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.
• Premium drive chain has gold-colored plates for outstanding looks.
• Wide-diameter fuel tank cap for easier refueling.
• Repackable exhaust silencer.
• Durable, comfortable handlebar grips.
