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. Based on the championship-winning YZ250F and boasting a wide range of cross-country features, the YZ250FX is a true “out-of-the-box” hare scramble/cross-country competition machine.

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.

INNOVATIVE 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.

CROSS COUNTRY FEATURES

With the electric starting system, a 8.2 litre 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.

2023 Yamaha YZ250FX Totalmotorcycle.com Key Features

• Out-of-the-Box 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.
• 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.
• 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.
• Selectable Fuel Maps
  Increasing the YZ250FX’s ability to tackle a wide range of riding environments, two optimized fuel injection maps—both of which can be loaded and tuned in the Yamaha Power Tuner App—are 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.
• High-Spec Braking Components
  The high performance braking system provides exceptional stopping power and control through high-spec componentry, including a rigid front caliper with larger diameter pistons, aggressive brake pad compound and a 270mm front rotor. The rear brake gets a lightweight rear caliper and hanger with a 240mm rear rotor to reduce unsprung weight.
• Sharp, Durable Graphics Scheme
  Sharp competition-inspired 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. Dark radiator louvers add to the aggressive look.
• 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.
