Key Features:

  • Our legendary two-stroke Supercross winner is more potent than ever.
  • 610 grams off the front end makes this the quickest turning, best-handling YZ250 ever.
  • A light, aluminum frame housing a patented YPVS™ Power valve-equipped ripper of an engine results in an awesome power-to-weight ratio.
  • Ready to race out-of-the-crate, complete with a ProTaper aluminum handlebar, titanium footpegs, gripper seat and Excel rims.


  • 249cc liquid-cooled reed-valve-inducted two-stroke engine is lightweight, compact and features an incredibly wide, hard-hitting powerband.
  • Patented YPVS™ power-valve system combines crisp, hard-hitting, bottom-end acceleration with strong midrange and eye-opening top-end.
  • Special-design carbon fiber reed-valve petals improve throttle response and engine performance across the entire rpm range.
  • Smooth-shifting, five-speed, close-ratio transmission with heavy-duty, multiplate clutch.
  • Primary kickstarter ensures smooth, easy starting action and reduced weight.
  • Large-capacity radiator features a ten-row core with four louvers for maximum cooling efficiency.
  • 38mm Keihin PWK carburetor with power jet and throttle position sensor (TPS) ensures precise fuel/air mixing and extra-crisp throttle response throughout the powerband.
  • Digital CDI ignition system delivers precise spark for faster, stronger response anywhere in the powerband.
  • 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 YZ250 the best handling in the 250 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 fully floating front and 245mm rear discs, deliver strong stopping power with progressive feel.
  • Lightweight 21-inch front and 19-inch rear Excel rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance and handling.
  • 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:

  • Wide, cleated, folding titanium footpegs are lightweight and provide excellent comfort, grip and ground clearance.
  • Special-design “gripper” type seat and fuel tank, forward-canted steering crown and low handlebar provide excellent movement and more comfortable ergonomics for riders.
  • Wide-diameter fuel tank cap ensures easier usage, while larger tank opening means faster, hassle-free refueling.
  • A light and strong ProTaper aluminum handlebar in adjustable mounts means comfort and control.
  • Use of light, box-head bolts throughout the chassis eases maintenance while reducing weight and increasing performance.
  • Repackable exhaust silencer.
  • Durable, comfortable handlebar grips.
