Yamaha off-road YZ125 2008

A light, aluminum frame housing an amazingly light and compact engine results in an awesome power-to-weight ratio. 500 grams off the front end makes this the quickest turning, best-handling YZ125 ever. Ready to race out-of-the-crate, complete with a ProTaper aluminum handlebar, titanium footpegs and gripper seat. A pure motocross machine, the light and nimble YZ125 is the perfect choice for riders stepping up from the 85cc class.

New for 2008

• New-design reed-valve spacer improves acceleration across the entire powerband.
• New, YZ250F-style front-brake caliper (-220 grams) and light, wave-type discs (-70 grams) front and (-70 grams) rear remove unsprung weight and provide excellent stopping power. A new, pushrod-type front master cylinder with a smaller piston serve up great braking power.
• Modifying thickness of outer fork tubes in the 48mm inverted fork result in a weight reduction of 200 grams. Revised damping settings provide fantastic bump absorption and comfort.
• A 120-gram lighter fork protector, axle bracket and the new front brake add up to a 500-gram lighter front end—and even quicker, lighter handling.
• Revised rear shock settings complement the ones in the fork.

Engine

• 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

• 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.
• Wide-diameter fuel tank cap for easier refueling.
• Repackable exhaust silencer.
• Durable, comfortable handlebar grips.
