Chassis / Suspension

• YZ250-BASED FRAME: Ultra-lightweight YZ250-spec frame features carefully engineered combination of aluminum castings, forgings and extrusions for the perfect balance of rigidity and flex. Removable aluminum rear subframe is constructed of square-section tubing for reduced weight.
• 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. Additionally, a adopted scraper between the dust and oil seal improves reliability in cross country conditions.
• 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.
• BRAKE SYSTEM: An updated high performance braking system features larger front pistons, a more rigid caliper and a redesigned 270mm front rotor with a 30% increase in pad contact area, 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, reducing unsprung weight with no compromise on performance.
• PREMIUM EXCEL® WHEELS & DUNLOP® TIRES: Slick blue Excel® rims provide exceptional durability and a premium look. They come wrapped in high performance Dunlop® Geomax MX33 tires for improved cornering traction, stability and feel.

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.
• TUNED FOR GNCC® COMPETITION: The YZ250X utilizes a revised compression ratio, revised YPVS™ timing and a model-specific digital CDI unit compared to its motocross sibling—all focused on creating a broad, usable power delivery specifically suited to cross country and enduro-style competition.
• AIR INTAKE DESIGN: Updated intake design allows for a straighter, more efficient draw of air into the intake tract.
• NARROW EXHAUST PIPE: Unique compact exhaust expansion chamber is designed especially for the YZ250X to improve both horizontal and vertical clearance on tight, technical trails while still providing excellent exhaust efficiency.
• WIDE-RATIO FIVE-SPEED TRANSMISSION: Smooth-shifting wide-ratio transmission ensures proper gearing from tight woods to wide-open fire roads.
• HIGH-CAPACITY RADIATOR: Large-capacity radiator with dark louvers deliver an aggressive look and maximum cooling efficiency for demanding racing conditions.

New For 2023

• IMPROVED RIDER ERGONOMICS: To increase rider confidence in challenging cross country conditions, smoothly integrated body panels, more narrow fuel tank design, slimmer shroud width and flatter seat all combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for better control.
• BOLD YZ STYLING: Along with the slimmer, more aggressive bodywork, a front and rear fender design and radiator shrouds all integrate with a bold graphics scheme to highlight the YZ family pedigree. Premium Yamaha graphics are now embedded to provide excellent durability and scratch resistance.
• BRAKE SYSTEM: An updated high performance braking system features larger front pistons, a more rigid caliper and a redesigned 270mm front rotor with a 30% increase in pad contact area, 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, reducing unsprung weight with no compromise on performance.
• CLUTCH PLATES: To improve clutch durability without compromising smooth operation, six inner pressure plates adopt a friction material with excellent heat resistance characteristics ideal for extended cross-country competition.To increase rider confidence in challenging cross country conditions, smoothly integrated body panels, more narrow fuel tank design, slimmer shroud width and flatter seat all combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for better control.
• REVISED SUSPENSION DAMPING: Further improving the YZ250X's already renowned suspension performance, front fork internals and revised suspension settings further improve bump absorption, cornering performance and comfort to better withstand the grueling demands of cross country and enduro-style racing.
• AIR INTAKE DESIGN: Further improving the YZ250X's already renowned suspension performance, front fork internals and revised suspension settings further improve bump absorption, cornering performance and comfort to better withstand the grueling demands of cross country and enduro-style racing.
