Underneath its sharp, aggressive YZ styling lies the most refined, balanced and competition-ready motorcycle in the 250 class.
Its light, compact chassis offers exceptional handling feel, a more comfortable riding position and best-in-class KYB® suspension.
Its renowned 250cc four-stroke engine churns out exhilarating power across the rev range, and combined with Yamaha’s advanced next-generation Power Tuner App, offers a level of tunability the competition can’t match.
Features
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.
Aluminium bilateral beam frame
An aluminium bilateral beam frame based on the flagship YZ450F 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.
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. 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.
Efficient Air Intake
Optimised intake path draws air from under the side covers and seat allowing for a compact body design. This profile allows radiator shrouds to be slim with the airbox cover to be low and narrow. The efficient intake path also boosts mid- to high-rpm engine performance.
Adjustable suspension settings
KYB suspension include optimised settings front and rear. The rear shock lever ratio is revised for added traction and stability. Plus a light spring rate is specced for the rear shock and delta-shaped piston shims in the fork for enhanced stability, traction and a planted feel. The front fork also features tool-free compression clickers for easy adjustment.
Traction control & launch control
The 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 Launch Control System features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 14,000 rpm for optimised launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.
Adjustable engine maps
The left 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.
