Lighter is better.
Now even lighter-new refinements along with an aluminum frame housing an amazingly compact engine results in the consummate combination of power and lightness no other 125 can match.
I loved the power delivery... it has a very smooth power band for a 125, a lot more torque then I expected from a 2-stroke. Don’t get me wrong though, this thing absolutely hauls! This thing just pulls from top to bottom. I loved how light this bike was. It seems like you can just flick it around, and the suspension is amazing, I love it. I had no problems wheeling and jumping, it really boosts your confidence. The main thing is this bike just goes, I’ve had no problems with it, it’s a rocket! No wonder almost every magazine named it 125 of the year!
This 2 stroke is a good beginner bike. The power is smooth so it is very controllable and won’t rip your arms off at the shoulder (if controlled properly). It sits a little tall so I wouldn’t recommend it for shorter riders, but if you use caution when testing the clutch and finding the power band and don’t open it up first try, it could be a great introduction into dirt bikes. Once you ride this bike you won’t be able to wipe the smile off your face!
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.
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.
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.
