FEATURED 2024 YAMAHA YZ250FX - YD8949

2024 Yamaha YZ250FX

YOUR POWER. YOUR WAY.
This Cross Country racer has all the features to win including the smartphone Power Tuner app that adjusts the bike's settings to fit your style and the track.

Features May Include:

• All-New Hare Scramble/GNCC® Racer
  Based on the championship-winning YZ250F that features Yamaha’s revolutionary front-intake, rear-exhaust, liquid-cooled, DOHC 4-stroke power plant with an added sixth gear, wide ratio transmission and a range of cross country upgrades, the YZ250FX is an “out-of-the-box” Hare Scrambles and GNCC® competition machine.
• Innovative Yamaha Power Tuner App
  Yamaha’s free-of-charge Power Tuner app puts the flexibility and precision tunability of the GYTR® Power Tuner into your smartphone. Make fueling and ignition timing changes instantly and upload them to the bike for ultimate track-side tuning while the handlebar-mounted map switch allows you to adjust pre-loaded engine maps on the fly.
• High Performance Four-Stroke Engine
  The compact, powerful YZ250FX engine includes all the same race-developed technologies of the championship-winning YZ250F, tuned for cross country performance. Revised intake duct, intake port, exhaust camshaft profile, muffler and balancer weight position combine to further improve power and usability across the entire rev range.
• Precisely Tuned Chassis
  The highly developed aluminum bilateral beam frame features precisely tuned flex characteristics for competition-ready performance. The forged section at the swingarm pivot, and improved engine mounting brackets provide a nimble lightweight feeling in tight, technical terrain while still providing control in fast sections. As always, Yamaha’s class-leading KYB® suspension ensures maximum control and traction.
• Cross Country Features
  With the electric starting system, a 2.16-gallon fuel tank, rugged plastic skid plate, 18-inch rear wheel and high performance Dunlop® Geomax MX33 tires, the YZ250FX is ready to win right out of the box.
• Competition-Ready Engine Performance
  The revolutionary front-intake/rear-exhaust, liquid-cooled, fuel-injected, four-stroke engine has been developed for victories in the highly competitive GNCC® and Hare Scrambles race series. Intake and exhaust ports work with a higher compression piston for a wider spread of power without losing top-end performance.
• Forward-Thinking Engine Design
  Reversing the cylinder head while placing the intake forward and the exhaust to the rear allow for a straight shot, downdraft intake and straight exhaust port for maximized engine performance.
• Innovative Yamaha Power Tuner App
  The free-of-charge Yamaha Power Tuner app brings the power of the GYTR® Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.
• Adjustable Engine and Fuel Mapping
  A handlebar-mounted map switch allows the rider to quickly select between two preloaded engine maps—loaded and tunable in the Power Tuner app—to account for changing riding conditions. The fuel injection system uses 3D-mapped electronic control for the fuel and ignition timing that are optimized for cross country racing. Pre-loaded maps include one for fast, aggressive high-traction conditions and one with a smoother engine character for extreme, low-traction conditions.
• Six-Speed Gearbox
  A six-speed transmission is used to ensure the right gear is available for the wide variety of terrain found in cross country racing. Updated gearing ratios and a heavy-duty, large-diameter clutch bring enhanced durability in the extreme conditions of a three-hour GNCC® race.
• Mass-Centralized Electric Starter System
  The YZ250FX features a compact, centrally-mounted electric starter system to minimize restart delays mid-race and add convenience everywhere else. Powered by a high-capacity lightweight four-cell lithium-ion battery, the system adds minimal weight.
• Slim Bodywork
  The compact bodywork eases the rider’s movement across the machine in tough terrain. The fuel tank provides 2.16 gallons of fuel with a larger fuel cap opening. New graphics are embedded in the body moldings for long-lasting good looks.
• Light and Strong Aluminum Frame
  An all-aluminum bilateral beam frame provides strength, lightness and durability for cross country racing conditions and comes standard with a rugged plastic skid plate.
• Advanced Suspension
  Industry favorite KYB® fully adjustable spring-type forks with speed-sensitive damping and a KYB® rear shock have been thoroughly tested and tuned specifically for cross country racing.
• Purpose-Built Tires
  Special cross country racing Dunlop® Geomax MX33 tires maximize traction while delivering excellent durability.
• High Performance Braking System
  Improved high-spec braking components now include more rigid front caliper with larger diameter pistons, more aggressive brake pad compound and a redesigned 270mm front rotor. The rear brake gets a lighter rear brake caliper and hanger with a 240mm rear rotor to reduce unsprung weight. Brake improvements provide exceptional braking control.
• Practical Touches
  Quick-adjust clutch, wide 55mm platform foot pegs, four-position rubber-mounted handlebar clamps, aluminum handlebars and a side stand come standard for added rider convenience. The YZ250FX is also pre-wired for an optional radiator fan for the most grueling conditions.
• Easy Servicing
  The air cleaner cover features tool-free access to the air filter. Thanks to a WR-style fuel level sensor in the tank, the YZ250FX includes a convenient low fuel indicator along with an engine warning indicator on the handlebar.
• Sealed O-Ring Chain
  High-quality O-ring chain is tough, durable and light.
• Improved Engine Performance
  Liquid-cooled 250cc four-stroke churns out stronger mid- to high-range power thanks to an improved air intake, wider intake port, redesigned exhaust camshaft, improved muffler and optimized ECU settings.
• Selectable Fuel Maps
  Increasing the YZ250FX's ability to tackle a wide range of riding environments, the ECU has been optimized with two improved fuel injection maps—both of which can be loaded and tuned in the Yamaha Power Tuner app—accessible through a handlebar-mounted map switch for on-the-fly adjustments to changing riding conditions. Pre-loaded maps include one for fast, aggressive high-traction conditions and one with a smoother engine character for extreme, low-traction conditions.
• Updated Braking Components
  Improved high-spec braking components now include more rigid front caliper with larger diameter pistons, more aggressive brake pad compound and a redesigned 270mm front rotor. The rear brake gets a lighter rear brake caliper and hanger with a 240mm rear rotor to reduce unsprung weight. Brake improvements provide exceptional braking control.
• Updated Bilateral Aluminum Frame
  The highly developed aluminum bilateral beam frame taken from the class-leading YZ250F has been tuned for cross country performance and modified to match the more powerful engine.
• Modified Balancer Position
  Position of the balancer weight has been adjusted to reduce vibration in the low- to mid-rpm range for less rider fatigue and increased long-distance comfort.
• New High-Capacity Muffler
  Improves high-rpm power delivery while providing a deep, throaty exhaust note.
• Sharp New Graphics Scheme
  New graphics scheme highlights the YZ's unmatched racing pedigree. Premium Yamaha Blue and dark blue graphics are embedded to provide excellent durability and scratch resistance.
