2025 Yamaha YZ250FX Bike

• Completely redesigned aluminum bilateral beam frame based on the class-dominating YZ250F
• Optimized intake path draws air from under the side covers and seat allowing for a lighter, slimmer and more compact body; this redesign allows radiator shrouds to be 50mm slimmer and the airbox cover to be lower and more narrow; the more efficient intake path also boosts mid- to high-rpm engine performance; controlled through the Yamaha Power Tuner App
• Revised ECU settings result in even more mid- to high-end power
• Redesigned cam chain for improved durability
• Revised rear brake line for improved feel
• All-new four-level Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction
• Updated Launch Control system features an RPM limiter which can be adjusted in 500 RPM increments between 6,000 and 14,000 for optimized launches when the gate drops; controlled through the Yamaha Power Tuner App
• New handlebar-mounted multi-function switch allows simple on-the-fly selection between two preloaded engine maps with the push of a button; pre-loaded maps include one for fast, aggressive high-traction conditions and one with a smoother engine character for extreme, low-traction conditions; maps are loaded and configured with the Power Tuner App
• Revised suspension settings: fork settings improve bump reaction to deliver an exceptional balance between cornering performance and high-speed stability; shock settings allow less pitch on corner entry/exit for improved stability
• Revised frame and suspension settings result in a lower center of gravity for improved maneuverability in tight, technical terrain
• New hand-adjustable knob for easy compression adjustments on fork, plus larger fork protectors
• New water-resistant PVC handlebar pad and seamless seat cover
• Slimmer, flatter body design for improved control, including a slimmer fuel tank, a 15mm lower airbox and 50mm narrower radiator shrouds for easier rider movement and cornering performance; the rider triangle is also improved with increased legroom between the seat and foot pegs for greater rider comfort
• Wraparound Rear-Positioned Exhaust Layout: exhaust pipe design improves mass centralization and power development characteristics; this layout moves the rear end of the exhaust pipe farther forward and positions the muffler closer to the bike’s center of mass
• Standard side stand and plastic composite skid plate
• Pre-wired for an optional radiator fan
• Embedded graphics to provide excellent durability and scratch resistance
• Power Tuner App puts the flexibility and precision tunability of the GYTR Power Tuner into your smartphone: adjust air/fuel mixture and ignition timing maps instantly and upload them to the bike for ultimate track-side tuning; intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, and lap timer, along with helpful engine and suspension tuning guides; record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more; wireless connectivity to the bike’s onboard CAN-bus network
