YAMAHA YZ250F MONSTER ENERGY 2025

Competition-Inspired Monster Energy® Styling

Roll like a factory pro with this striking Monster Energy® Yamaha Racing Edition. Inspired by Yamaha’s factory race team, iconic blue and black Monster Energy® livery combines with the YZ250F’s sleek, aggressive bodywork for a competition-ready look and feel.

Advanced 250cc Four-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.

Piston, Rod & Crankshaft Balance

A forged piston features a bridge-box design for maximized strength with minimal weight. The piston, rings and DLC-coated piston pin, along with the offset cylinder configuration, all reduce friction loss. Intake ports, cam profiles, high-strength connecting rod, optimized crank and counter-balancer all work together to produce potent high-rpm power with user-friendly delivery and exceptional reliability.

Advanced Fuel Injection

The adjustable fuel injection system uses a 44mm throttle body, fed by a high-pressure electric fuel pump, to inject fuel through a 12-hole Denso® injector. This ensures optimum fuel atomization and air/fuel calibration for excellent rideability in a wide range of riding conditions.

Innovative New Yamaha Power Tuner App

The free-of-charge Yamaha Power Tuner App brings the power of the GYTR® Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard electronics system, the app allows owners to adjust air/fuel mixture and ignition timing to tune engine character for track conditions, log track set-up information, and monitor a range of data such as maintenance and system diagnosis, engine run time and more. The user-friendly app also features an intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, lap timer, along with helpful engine and suspension tuning guides.

Adjustable Engine Maps & New Switchbox

A newly designed handlebar switchbox 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, and a new raised rib helps the rider avoid pressing the wrong button while wearing gloves. Maps are loaded and configured within the Yamaha Power Tuner App.

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 updated Launch Control System now features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 14,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.
