Chassis / Suspension

• HIGH PERFORMANCE BRAKING SYSTEM: Lightweight braking system features larger front pistons, a more rigid caliper, a redesigned 270mm front rotor with a 30% increase in pad contact area and higher friction pad material, all combining to provide exceptional braking power and feel. The redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, further reducing unsprung weight with no compromise on performance.
• INDUSTRY-LEADING KYB® FORK: The fully adjustable KYB® 48mm forks feature the Speed-Sensitive System which uses piston speed to control the damping force for super-precise handling, superb bump absorption and 11.8 inches of suspension travel.
• ADVANCED KYB® SHOCK: Fully adjustable KYB® shock features reduced-friction Kashima Coat™ 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. It all adds up to fantastic rear wheel control and a sweet ride.
• ALUMINUM FRAME: A carefully engineered, advanced aluminum frame and swingarm give the YZ250 class-leading track performance.
• LIGHTWEIGHT SUBFRAME: Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
• EXCEL® RIMS: Lightweight 21-inch front and 19-inch rear Excel® rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance and sharp handling.
• RACE-READY TIRES: Premium Dunlop® Geomax MX33 tires offer race-developed performance on a wide range of terrain.

Engine

• EXHILARATING TWO-STROKE POWER: The 249cc liquid-cooled reed-valve-inducted two-stroke engine is lightweight, compact and fun, with an incredibly wide, hard-hitting powerband.
• YAMAHA POWER VALVE SYSTEM: Patented YPVS™ combines crisp, hard-hitting bottom-end acceleration with strong mid-range and top-end.
• ADVANCED CARBURETOR: Advanced 38mm Hitachi Astemo® Keihin PWK38S carburetor with power jet and throttle position sensor provides precise fuel/air mixing and extra-crisp throttle response.
• RACE-DEVELOPED INTAKE: Special-design carbon fiber reed-valve petals improve the throttle response and engine performance across the entire rpm range.
• CLOSE-RATIO TRANSMISSION: Smooth-shifting, five-speed, close-ratio transmission with a heavy-duty, multiplate clutch ensure confident gear changes in all conditions.
• HIGH-CAPACITY RADIATOR: Large-capacity radiator features a ten-row core with updated louver design for maximum cooling efficiency.
• DIGITAL IGNITION: Digital CDI system delivers precise spark for faster, stronger response anywhere in the rev range.

Other Features

• RACE-READY FEATURES: Complete with an aluminum handlebar, two-position adjustable handlebar clamp, wide foot pegs, gripper seat and adjustable clutch lever with works-style cable adjuster, the Monster Energy® Edition YZ250 is competition-ready straight out of the crate.

Top Features

• MODERN MONSTER ENERGY® YZ STYLING: Aggressive, race-inspired styling—from the sharp new bodywork including front and rear fenders, radiator shrouds and number plates, to the smaller details like fork guards, rear brake disc and caliper protectors, and wide foot pegs—spotlights the YZ250's extensive two-stroke racing pedigree from every angle. A Monster Energy®‑inspired graphics package completes the factory-ride look and feel.
• IMPROVED RIDER ERGONOMICS: A new flatter seat and more narrow fuel tank design, along with smoothly integrated body panels and slimmer shroud width, combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence.
• HIGH PERFORMANCE BRAKING SYSTEM: Lightweight braking system features larger front pistons, a more rigid caliper, a redesigned 270mm front rotor with a 30% increase in pad contact area and higher friction pad material, all combining to provide exceptional braking power and feel. The redesigned rear rotor maintains the same braking power while dropping outer diameter from 245mm to 240mm, further reducing unsprung weight with no compromise on performance.
• REVISED SUSPENSION DAMPING: Further improving the YZ250's already renowned suspension performance, front and rear suspension has been revised to further improve bump absorption and cornering ability. KYB® inverted front fork now includes a leaf spring in the mid-speed valve for increased performance and comfort.
• AIR INTAKE DESIGN: Updated intake design allows for a straighter, more efficient draw of air into the intake tract.
• EXHILARATING TWO-STROKE POWER: The 249cc liquid-cooled YPVS™-equipped reed-valve-inducted two-stroke engine is lightweight, compact and fun, with an incredibly wide, hard-hitting powerband.
• LIGHTWEIGHT FRAME: A carefully engineered, advanced aluminum frame and swingarm give the YZ250 class-leading track performance.
• RIDER-FRIENDLY CHASSIS: Well-tuned chassis and ultra-light weight means intuitive handling, less rider fatigue, and a confidence-boosting sense of control.
• HIGH PERFORMANCE BRAKING SYSTEM: Lightweight braking system features larger front pistons, a more rigid caliper, a redesigned 270mm front rotor with a 30% increase in pad contact area and higher friction pad material, all combining to provide exceptional braking power and feel.
