Advanced 250cc Four-Stroke Engine

Featuring a high-spec piston, aggressive cam profiles and forward positioned intake cylinder head layout, the YZ250F's advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque. New for 2024, a more efficient intake path and revised ECU settings results in even more mid- to high-end power.

All-New Aluminum Bilateral Beam Frame

A completely redesigned aluminum bilateral beam frame based on the flagship YZ450F provides just the right amount of strength and flex for the perfect balance of straight-line stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction, allowing the rider to charge corners with greater confidence.

Class-Leading Suspension

Fully adjustable KYB® coil spring-type fork with speed-sensitive damping delivers exceptional balance between handling and bump absorption for championship-winning performance. New for 2024, the fork now includes hand-adjustable knob for toolless compression adjustment. Linkage-type rear suspension features a KYB® shock with revised settings to provide less pitch on corner entry/exit and improved stability.

High Performance Braking System

A large 270mm front brake disc and 240mm rear are coupled with a Nissin calipers to provide exceptional stopping power and control.

Innovative Yamaha Power Tuner App

Yamaha’s industry-leading Power Tuner App puts the flexibility and precision tunability of the GYTR® Power Tuner into your smartphone. Make fueling and ignition timing changes on the app, then instantly upload them to your bike for ultimate track-side tuning. Now even more user-friendly, new features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, lap timer, along with helpful engine and suspension tuning guides. Best of all, it's free-of-charge.

Slimmer Body & Improved Ergos

The new 2024 YZ250F has a slimmer, flatter body design for improved control, including a more narrow fuel tank, lower airbox and more narrow radiator shrouds. The rider triangle is also improved with increased legroom between the seat and footpegs for greater rider comfort.
