Yamaha YZ250F
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.
The aluminium bilateral beam frame has been completely redesigned based on the flagship YZ450F and provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lightweight feel and increased front wheel traction, allowing the rider to enter corners with greater confidence and more line choices.
Advanced 250cc 4-stroke Engine
The YZ250F's liquid-cooled, DOHC 4-valve, fuel-injected powerplant features a forward-positioned straight downdraft intake with symmetrical intake ports, high- spec piston and aggressive cam profiles. The 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.

Yamaha Power Tuner App
Like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner App is revised to be 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.
Revised Suspension Settings
Class leading, 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 for improved stability.
New Air Intake
Optimised intake path draws air from under the side covers and seat allowing for a lighter, slimmer and more compact body. This redesign allows radiator shrouds to be slimmer and the airbox cover to be lower and more narrow. The more efficient intake path also boosts mid- to high-rpm engine performance.
New Traction Control & Launch Control
The all-new Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction. Three levels can be selected: HIGH, LOW or OFF. The updated Launch Control System now features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 pm and 14,000 pm for optimised launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.
Adjustable Engine Maps
New handlebar-mounted switch allows on- the-fly selection between two preloaded engine maps with the push of a button, making it easy to make immediate adjustments to changing track or weather conditions. Maps are loaded and configured within the Power Tuner App.
Strong, Lightweight Wheels
Careful computer-aided refinement of
each wheel's cross-sectional profile
shaves valuable weight without sacrificing
durability. Unique three-cross-spoke
pattern on the rear wheel improves impact
absorption and overall feel.
