Features
Miscellaneous
Engine:
• 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.
Chassis/Suspension:
• YZ250F-style front-brake caliper and wave-style front and rear discs minimize unsprung weight and provide excellent stopping power. • The KYB® 48mm forks feature the Speed-Sensitive System that uses piston speed to control damping force for super-precise handling and a smooth ride. • A carefully engineered, advanced aluminum frame and swingarm give the YZ250 the best handling in the 250 class. • Removable aluminum rear subframe is constructed of square-section tubing for reduced weight. • Rear, fully adjustable KYB® 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 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. • Premium drive chain has gold-colored plates for outstanding looks. • Use of light box-head bolts throughout the chassis eases maintenance while reducing weight and increasing performance. • Repackable exhaust silencer. • Durable, comfortable handlebar grips.
