2006 Yamaha YZ250

Key Features:

  • 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 Renthal aluminum handlebar, titanium footpegs, gripper seat and Excel rims
  • Winner of "Cycle World", "Racer X" and "Motocross Action" shootouts.


New for 2006:

  • Speed sensitive system, 48mm Kayaba fork tubes move the TCV (transfer control valves) above the fork springs, so that damping force is now controlled by piston speed. Along with a bigger base valve hole, the result is a smooth ride and super-precise handling.
  • A thicker rear shock rod, a super-light titanium shock spring, reduced-friction Kashima coating of internals and a revised swingarm all work together for fantastic rear wheel control and a sweet ride.
  • Increased fork pitch, also gives great handling.
  • Carburetion revisions and a new exhaust pipe meet FIM requirements and produce arm-stretching, broadband power.
  • Light and strong Renthal aluminum handlebar in new clamps with 10mm of adjustability.
  • Aggressive new front fender and front number plate up the style factor.
  • Tapered rear wheel spacers ease sliding the rear wheel into place, for quicker tire changes.


Engine:

  • Liquid-cooled, 249cc, 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 topend.
  • Special-design carbon fiber reed-valve petals improve throttle response and engine performance across the entire RPM range.
  • Smooth-shifting, 5-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) ensure precise fuel/air mixing and extra-crisp throttle response throughout the powerband.
  • Digital CD 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.


Chassis/Suspension:

  • An aluminum frame and swingarm produce big weight savings, giving YZ250 the best handling in the 250 class.
  • 48mm fork with TCV (transfer control valve) for stable damping, improved mid- to full-stroke performance and great rider feedback.
  • Removable aluminum rear subframe constructed of square-section pipe for reduced weight.
  • Rear, fully adjustable Kayaba shock with 12.4 inches of travel, separate adjusters for high- and low-speed compression damping, and a full lock oil rebound system for increased comfort.
  • 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.
  • Premium Dunlop D756 knobbies offer race-spec traction and wear.


Additional Features:

  • Wide, cleated, folding titanium footpegs are lightweight and provide excellent comfort, grip and ground clearance.
