Specifications

Features

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.

All-New 450cc Four-Stroke Engine The new 2023 YZ450F's engine has been completely redesigned, now with a 500 rpm higher rev limit. Among the changes are new exhaust and intake port shapes, larger diameter titanium intake valves, new piston, cylinder, crankshaft and balancer assembly, and a switch from wet sump to dry sump lubrication. The combined effect of these features is more power across the entire rev range in a lighter, more compact engine.
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 CAN-bus network, the app allows owners to adjust air/fuel mixture and ignition timing 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. New for 2023, the app has been revised to be more user-friendly. New features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, lap timer, along with engine and suspension tuning guides. Additionally, new lightweight handlebar-mounted switchgear allows on-the-fly selection of preloaded engine maps.
New Traction Control & Updated Launch Control An 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 continues to implement traction control and now features an rpm limiting setting, which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm. Both systems are controlled through the new Yamaha Power Tuner App.
Advanced Fuel Injection The engine breathes through a 44mm Mikuni® throttle body fed by a high-pressure electric pump to ensure optimum fuel atomization and power for a wide range of riding conditions. The ultra-compact throttle body also saves weight and improves mass-centralization.
New Compact Lightweight Clutch The all-new clutch design replaces the coil springs of the previous model with a new disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smoother engagement and excellent feel. A new clutch cover employs a stylish geometric design that helps minimize scratching and lends a premium look.
New Five-Speed Transmission All new tri-shaft transmission layout vertically stacks the transmission shafts, raising the center shaft and forming a triangle between the crank, drive shaft and main shaft for a lighter, more compact transmission.
New Air Intake Optimized intake path draws air from under the side covers and seat allowing for a lighter, slimmer and more compact shroud area. This redesign allows the airbox cover to be lower and more narrow and radiator shrouds to be slimmer.
Electric Starter System The YZ450F features a compact electric starter system to minimize restart delays on track and add convenience everywhere else. Powered by a high-capacity and ultra-lightweight four-cell lithium-ion battery, the system adds minimal weight.

All-New Aluminum Bilateral Beam Frame Striking the perfect balance of precise cornering performance and handling stability, the completely redesigned aluminum bilateral beam frame consists of more than 10 different aluminum components welded together. This provides the opportunity to carefully tune rigidity and flex characteristics of each component to ensure competition-level performance. The result is a better handling machine with lighter feel, improved bump absorption and increased traction, allowing the rider to enter corners with greater confidence and more line choices.
Revised Class-Leading Suspension High-spec fully adjustable Speed Sensitive System KYB® coil spring-type fork provides exceptional bump absorption. The linkage-type rear suspension features a KYB® shock with damping characteristics to match the new YZ450F's chassis. Newly revised internal valving works in combination with the new frame and body to improve traction and increase cornering performance. Additionally, the front fork now features a new hand operated compression damping adjuster for simple, toolless adjustments.
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.
Strong, Lightweight Wheels Careful computer-aided design of each wheel’s cross-sectional profile shaves weight without sacrificing durability. The YZ450F's rear wheel comes laced with a three-cross-spoke pattern for improved impact absorption and rider feel.
Triple Clamp with Adjustable Handlebar Mounts The top triple clamp design balances rigidity for improved steering feel while the four-position adjustable handlebar clamp is rubber-mounted for comfort, reduced handlebar vibration and easily tunable bar position.

The Ultimate Open Class YZ The reigning pro Motocross & Supercross champ now raises the bar even higher. Building on its best-in-class power delivery and suspension performance, the all-new 2023 YZ450F boasts even more power, better handling, less weight, a new more narrow body with improved ergonomics and next-generation Power Tuner app—all while maintaining its renowned ease-of-use that makes fast riders even faster.
All-New 450cc Four-Stroke Engine Lighter, more compact with increased power across the entire rev range, the all-new 450cc engine maintains the YZ450F's exceptional pulling power and renowned ease-of-use, all while boosting the rev limit by 500 rpm for even more top-end power.
