Purpose-Built Off-Road Weapon
With its revamped chassis and enhanced ergonomics, the new YZ250FX is lighter, sharper, and more agile than ever. The perfect weapon for carving up cross-country courses.
Features may include:
New for 2025
All-New Aluminum Bilateral Beam Frame
A completely redesigned frame, based on the class-dominating YZ250F, strikes the perfect balance of strength and flex for improved cornering stability and control. The result is a lighter feel, increased front-wheel traction, and better handling in tight terrain.
New Air Intake System
A redesigned intake system draws air from under the side covers and seat, creating a slimmer and more compact body. Radiator shrouds are 50mm slimmer, improving ergonomics and airflow while enhancing mid- to high-rpm engine performance.
Updated Yamaha Power Tuner App
Yamaha’s groundbreaking Power Tuner App has been revised for an even more user-friendly experience. New features include an intuitive "Simple Tuning" slide bar for engine mapping, Traction and Launch Control tuning, lap timer functionality, and detailed engine and suspension tuning guides.
