SEE THE LIGHT
You might want to tell the opposition to take a good look now… When you bring the YZ125’s lean, lightweight chassis and supreme combination of engine suspension and brake performance to bear, it might be all they can do to keep you in sight.
That’s because that after years on top, the YZ125 is still the straight-A performer of its class.
The YZ’s amazingly compact and powerful engine nestles in a light, aluminium frame with just the right amount of flex where you need it.
Lean and scalpel sharp, the YZ125’s flexible power delivery means it is still among the smartest launching platforms from which for a young junior motocross rider to learn the tricks of the sport.
And because it comes in that shade of Factory Racing Blue that denotes it as a Yamaha, you can be sure it is designed to last every bit as well as it performs.
Key Features:
♦ Newly designed reed valve and spacer creates greater inlet efficiency and improved engine performance.
♦ Smaller, more compact muffler generates a 15% weight reduction over the 2007 part.
♦ Adopting the same fork inner tube as the ’07 YZ250F shaves precious grams and contributes to a smoother ride. Plus newly designed axle bracket, outer tube and fork tube protector further reduces weight.
♦ Revised damping settings to shock further improves bump compliance and tracking.
♦ Lightweight front brake master cylinder, caliper and lever is adopted for improved performance, brake feeling and reduced weight.
♦ Brand new wave-type front and rear disc rotors reduce weight and improve brake feeling.
♦ Ready to race out of the crate, complete with a ProTaper aluminium 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 80cc class, or just wanting a pure motocross experience.
♦ Adjustable handlebar clamps allow customization of fit for more compact pilots.
New for 2008:
♦ A pure motocross machine, the light and nimble YZ125 is the perfect choice for riders stepping into the 125 class.
♦ Amazingly compact 124cc reed valve-inducted two-stroke super light, with highly efficient straight intake and exhaust tracts.
♦ A carefully engineered, advanced aluminum frame and swingarm give the YZ125 the best handling in the class.
