COMPETITION DOMINATION
Riding into 2027 with the most Supercross and Motocross championships, the most shootout wins, and a legacy of dominance, the all-new YZ250F changes the game … again. Welcome to advanced moto technology with a new engine producing more power across the rev range, enhanced handling thanks to its new state-of-the-art aluminum frame, compact ergonomics and updated bodywork and unmatched smartphone tuneability.
Chassis / Suspension
- BOLT-FASTENED BRAKE PEDAL: The rear brake pedals have replaced rivets with bolts for easier replacement and maintenance.
- CLASS-LEADING KYB SUSPENSION: Front and rear KYB suspension, including a rear shock with a base valve, piston and tool-less low speed compression adjuster, offers increased damping force, shock absorption and comfort that enhances overall traction.
- IMPROVED BRAKE DISC MOUNTING: A brake disc mounting design to both the front and rear discs improves braking reliability.
- LIGHTWEIGHT REAR BRAKE: A rear brake system has been revised to create a linear buildup of stopping power while providing significant weight savings.
- PRECISE REAR BRAKE MASTER CYLINDER: A smaller and lighter rear brake master cylinder and caliper provides optimized braking force and controllability.
- RIGID, EASY-GRIP REAR FENDER: A rear fender provides ample rigidity and provides a secure place to grip the YZ250F when picking it up.
- TWO-TONE TWO-PIECE SIDE COVERS: Two-piece, two-tone side covers highlight the YZ series design, while standardized bolt heads offer easier installation and removal.
- YZ450F-DERIVED COMPACT FRAME: The 2027 YZ250F has adopted the YZ450F frame design, improving handling and cornering performance, along with a reassuring front-end feel.
Engine
- ADJUSTABLE LAUNCH CONTROL: An adjustable Launch Control System controlled through the Power Tuner App optimizes launches when the gate drops.
- HIGH-REVVING 250CC ENGINE: The YZ250F’s 250cc four-stroke engine increases power and torque across the entire rpm range, boasting a higher redline for more aggressive performance.
- DOUBLE-SPRING INTAKE VALVES: Intake valve springs feature the first double-spring design on a YZ Series model, improving stability to balance the higher-revving engine.
- DRY SUMP LUBRICATION SYSTEM: A dry sump lubrication system provides stable oil circulation, improving the durability and reliability for the higher engine output.
- ECU ANTI-THEFT LOCK: An ECU lock function through the Power Tuner App helps prevent theft and unauthorized engine start-up.
- INCREASED-AIRFLOW INTAKE PORT: A optimized intake port shape increases airflow, while compression ratios have been raised accordingly.
- NOISE COMPLIANT DESIGN: The intake and exhaust design is now noise compliant with FIM/AMA regulations at a comfortable noise level.
- OPTIMIZED ENGINE BRACKETS: Engine brackets for the engine and frame optimize rigidity for a more manageable character with predictable responsiveness.
- SMOOTH-OPERATING HYDRAULIC CLUTCH: The YZ250F adopts the YZ450F’s hydraulic clutch, along with a clutch hose specific to the YZ250F, with an increased clutch spring load for smooth feathering and engagement.
- THREE-LEVEL TRACTION CONTROL: A three-level Traction Control System selectable within the Yamaha Power Tuner App maintains ideal rear wheel traction.
- YZF-R1-INSPIRED ROCKER ARMS: Rocker arms inspired by Yamaha’s supersport YZF-R1 combined with finger-follower intake valves increase the rev limit by 700 rpm.
Key Features
- 250CC FOUR-STROKE ENGINE WITH NOISE COMPLIANCE: The 2027 YZ250F receives a liquid-cooled, DOHC, 4-valve, fuel-injected 250cc powerplant revised to increase power across the entire range with a rev limit 700 rpm higher than before. Despite the increase in power, a revised air cleaner and exhaust system reduces overall noise for FIM/AMA compliance, with a tuned exhaust note that’s pleasing to the ear.
- HYDRAULIC CLUTCH WITH CONSISTENT, DEPENDABLE PERFORMANCE: A hydraulic clutch adopted from the YZ450F performs consistently for stable, dependable performance. An increased springload reduces the strength needed to pull in the lever, providing smooth feathering and engagement characteristics on par with a cable-clutch.
- ADVANCED ALUMINUM BILATERAL BEAM FRAME: The 2027 YZ250F adopts the YZ450F’s compact aluminum bilateral beam frame, providing the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction allowing the rider to enter corners with greater confidence and more line choices.
- CLASS-LEADING KYB SUSPENSION: Front and rear KYB suspension, including a rear shock with a base valve, piston and tool-less low speed compression adjuster, offers increased damping force, shock absorption and comfort that enhances overall traction.
- COMPACT AND LIGHTWEIGHT REAR BRAKE SYSTEM: A rear braking system provides linear stopping power with improved braking force and controllability in a smaller, lighter package. The size of the rear brake caliper and master cylinder pistons have been reduced, as well as the diameter of the rear brake disc. The brake hose material and disc rotor bolts have also been revised resulting in 180g of weight savings.
- UPDATED YZ-SERIES BODYWORK FOR AN AGILE LOOK: The 2027 YZ250F shares bodywork with the YZ450F, evoking YZ styling with an agile look. A compact numberplate, two-tone, two-piece side covers, a rigid rear fender, and a seat with a honeycomb-patterned surface with optimal seat grip create a dynamic look with a clean compact appearance.
New For 2027
- 250CC FOUR-STROKE ENGINE: 250cc four-stroke engine increases power across the entire rpm range while reducing overall noise for FIM/AMA compliance.
- REDESIGNED REAR BRAKING SYSTEM: Rear braking system provides linear stopping power with improved braking force and controllability in a smaller, lighter package.
- SMOOTH-OPERATING HYDRAULIC CLUTCH: Hydraulic clutch adopted from the YZ450F, along with a clutch hose specific to the YZ250F, contributes to its light, responsive operation.
- TWO-PIECE SIDE COVERS: Two-piece side covers offer easier maintenance while providing striking two-tone YZ styling.
- YZ450F-DERIVED COMPACT FRAME: The 2027 YZ250F adopts the YZ450F’s compact frame design for improved handling and cornering performance.
Other Features
