2024 Yamaha YZ250F 50th Anniversary Edition Bike

• All-new aluminum bilateral beam frame based on the flagship YZ450F
• New air intake; optimized intake path draws air from under the side covers and seat allowing for a lighter, slimmer and more compact body, which allows radiator shrouds to be slimmer and the airbox cover to be lower and more narrow; also boosts mid- to high-rpm engine performance
• Sleek air cleaner cover provides tool-free access to the air filter, positioned at the front of the bike to avoid roost from the rear wheel
• Revised ECU settings for more mid- to high-end power
• Redesigned cam chain for improved durability
• New Traction Control system communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction; three levels can be selected: HIGH, LOW or OFF; controlled through the Yamaha Power Tuner App
• Updated Launch Control system now 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 Yamaha Power Tuner App, revised to be even more user-friendly; new features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, and lap timer, along with helpful engine and suspension tuning guides
• 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; 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
• Revised suspension settings: fork now includes hand-adjustable knob for tool-less compression adjustment; shock features revised settings to provide less pitch on corner entry/exit for improved stability
• Slimmer body and improved ergonomics with a slimmer, flatter body design for improved control, including a more narrow fuel tank, lower airbox, and more narrow radiator shrouds; rider triangle is also improved with increased legroom between the seat and footpegs for greater rider comfort
• Adjustable Engine Maps: two-mode adjustable engine mapping allows the rider to adjust engine character with the push of a button, making it easy to make immediate adjustments to changing track or weather conditions
• Wraparound Rear-Positioned Exhaust Layout: innovative 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
• Iconic heritage YZ styling: the YZ250F 50th Anniversary Edition draws its inspiration from 1990s-era Yamaha two-stroke motocrossers to honor 50 years of Yamaha off-road innovation and bold Yamaha MX style
