Based on the championship-winning 2020 YZ250F™, featuring 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/GNCC® competition machine.
Yamaha’s exclusive 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 the ultimate in track-side tuning. And for 2020, a handlebar-mounted map switch allows you to adjust preselected engine maps on the fly.
The engine is based on the championship-winning 2020 YZ250F, and includes all the same race-winning technologies. The cylinder head, exhaust system, fuel injection, drivetrain, electrical system and more were updated to offer improved power across the rev range. Together, the result is improved peak power, better power delivery, and even tougher durability.
With the electric starting system, a 2.16-gallon fuel tank, rugged plastic skid plate, 18-inch rear wheel and XC racing tires, the YZ250FX is ready to win right out of the box.
