- New 450cc Four-Stroke Engine
The completely redesigned 450cc liquid-cooled DOHC four-stroke engine is lighter, more compact and features stronger pulling power across the entire rev range. The rev limit is also increased by 500 rpm for longer over-rev while still maintaining the YZ450F’s broad power character.
- New Yamaha Power Tuner App
Yamaha’s industry-leading Power Tuner App has been extensively updated, retaining the full functionality of the previous version but now even easier to understand, easier to use, with more functionality. Engine mapping can now be made using an intuitive new slide bar. There is also a new lap timer, Traction and Launch Control tuning, and bike set-up guides. Best of all, it’s free-of-charge.
- New Traction Control & Updated 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 rpm and 11,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.
- All-New Aluminum Bilateral Beam Frame
A completely redesigned aluminum bilateral beam frame 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 lighter feel, more agility and increased traction allowing the rider to enter corners with greater confidence and more line choices.
- Class-Leading Suspension
High-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork provides exceptional bump absorption. New for 2023, the front fork now features toolless compression clickers for easy adjustment. The linkage-type rear suspension features a KYB® shock with revised damping characteristics to match the new YZ450F’s chassis.
- High Performance Braking System
A large 270mm front brake rotor is coupled with a Nissin caliper to provide excellent braking performance. Out back, rear brake feel is improved by reducing the rigidity of the brake hose providing a wider range of control at the pedal.
- Slimmer Body & Improved Ergos
A new slimmer, flatter and more compact body eases rider movement for improved control, including more seamless, rounded features from seat edges and side covers to a more narrow fuel tank and front shroud. The rider triangle is also improved with increased legroom between the seat and footpegs, and revised handlebar position for a more natural posture and enhanced rider comfort.
