2023 Yamaha YZ250F: DOMINATE THE TRACK.
Introducing the new 2023 Yamaha YZ250F…
The multi‑championship‑winning YZ250F dominates on the race track, at the shootouts and basically everywhere it goes.
The multi-championship-winning YZ250F dominates on the race track, at the shootouts and basically everywhere it goes. And with the Monster Energy Yamaha Racing Edition, privateers can have that factory look whether on the practice track or the starting gate.
YZ250F
With an outstanding track record that includes numerous MX2 Grand Prix race wins as well as a string of 250 Supercross titles in the USA, the YZ250F is born to win. And with its reduced unsprung weight and refined suspension performance, this high-tech motocross weapon is sharper, quicker and smoother – ready to own the podium.
Tune. Race. Win.
A key feature of the YZ250F is the high-tech reverse head 250cc engine. Its unique front facing inlet forces fresh air into the fuel injector to give you holeshot-winning acceleration and instant power whenever you need it. And this compact engine layout contributes significantly towards the bike’s agile handling by centralising mass.
When track surfaces or the weather changes, the Power Tuner app enables you to adjust your YZ250F’s engine settings from smooth through to aggressive. The SSS (Speed Sensitive System) front forks and race-proven monocross suspension feature new low speed damping settings – while the sophisticated aluminium chassis with its inbuilt balance of rigidity provides plenty of feedback. Fast, agile and smart, the tuneable YZ250F is built to deliver the ultimate performance at every track.
YZ250F
Motocross is one of the toughest sports there is. If you want to succeed you’ve got to grab every opportunity to sharpen your performance. Because every second counts. And the YZ250F’s reverse head engine delivers holeshot-winning acceleration and instant power that enables you to constantly outsmart the opposition.
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/exhaust ports, high-spec piston, aggressive cam profiles and reversed cylinder head layout. The advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque.
INNOVATIVE 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 CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more.
ADVANCED BILATERAL ALUMINUM FRAME
The YZ250F’s aluminum bilateral beam frame features main spars, engine mounts and mounting position that are designed to centralize mass and provide an ideal balance between cornering feel and straight-line rigidity.

ENGINE
- 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, aggressive cam profiles and reversed cylinder head layout. The advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque. - Innovative 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 CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing maps to tune engine performance for track conditions, record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more. - Adjustable Engine Maps
Two-mode adjustable engine mapping allows the rider to adjust engine character with the push of a button, making it easy to make immediate adjustments to changing track or weather conditions. - Piston, Rod & Crankshaft Balance
A flat-top forged piston features a bridge-box design for additional strength with minimal weight. The piston, rings and DLC-coated piston pin, along with the offset cylinder configuration, all reduce friction loss and contribute to quick response. The engine’s intake ports, cam profiles, high-strength connecting rod and 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. - Wraparound Rear-Positioned Exhaust Layout
An innovative exhaust pipe design improves mass centralization and power development characteristics. This layout moves the rear end of the exhaust pipe farther forward and positions the muffler closer to the bike’s center of mass. - Durable Transmission
The transmission gears, dogs and shift mechanisms are designed to smooth gear changes and improve durability under the heavy demands of motocross racing. The YZ250F also features a large-diameter clutch to boost reliability even further under high-heat conditions.
CHASSIS/SUSPENSION
- Advanced Bilateral Aluminum Frame
The bilateral aluminum frame features flex characteristics that give riders the ultimate combination of precise cornering performance and handling stability. Large upper frame bracing improves rigidity and durability. The wider rear frame spars, and the YZ250F-specific engine mounts centralize mass for the best possible balance of impact absorption, stiffness and feeling of grip. - 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. The linkage-type rear suspension features a KYB® shock optimized to provide less pitch on corner entry/exit and improved stability. - High Performance Braking System
Rigid front caliper, large-diameter pistons and large 270mm front brake rotor is the same system fitted to the YZ450F. Compact rear caliper works with a 240mm rotor and aggressive pad material for exceptional stopping power and braking control. - Compact Body & Seat Design
The YZ250F utilizes compact bodywork from tip to tail, including a narrow fuel tank specifically designed for motocross demands. In addition to shaving weight, the body design provides more comfortable knee grip for better control, with a seat shaped to give the rider additional room to move aboard the machine. - Enhanced Mass-Centralization
The compact engine, wraparound exhaust and fuel tank are strategically positioned to enhance mass centralization for a lightweight handling feeling on the track. The wide 55mm footpegs help lower the rider’s center of gravity for improved balance, control and rider comfort. - Reduced Unsprung Weight
Lightweight rear hub, rear sprocket and drive chain reduce unsprung weight and driveline inertia, contributing to more agile handling. - Strong, Lightweight Wheels
Careful computer-aided refinement of each wheel’s cross-sectional profile shaves valuable weight without sacrificing durability. Three-cross-spoke pattern on the rear wheel improves impact absorption and overall feel.
ADDITIONAL FEATURES
- Race-Winning Details
The YZ250F boasts top-spec details including 1-1/8-inch aluminum tapered handlebars secured to four-position adjustable handlebar mounts, wide 55mm footpegs, a quick-adjust clutch perch, stylish blue rims and a lightweight gold drive chain. - Simplified Servicing
Sleek air cleaner cover provides tool-free access to the air filter, positioned at the front of the bike to avoid roost from the rear wheel.
