Lighter, Slimmer, Sharper, Faster! Yamaha has taken the class-leading YZ450F and made it even better. Introducing the all-new 2023 Yamaha YZ450F motocross bike, with enhanced overall stability and more agility than ever before.
Take a look at the key features of the new bike…
- 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. - Slimmer Body and 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.
- 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 and 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 a rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm for optimised launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App. - All-New Aluminium Bilateral Beam Frame
A completely redesigned aluminium 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 tool-less 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 calliper 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. - Advanced Fuel Injection
The engine breathes through a 44mm Mikuni throttle body fed by a high-pressure electric pump to ensure optimum fuel atomisation and power for a wide range of riding conditions. The ultra-compact throttle body also saves weight and improves mass-centralisation.
- 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 minimise scratching and lends a premium look. - New Five-Speed Transmission
All new tri-shaft transmission layout vertically stacks the transmission shafts, raising the centre shaft and forming a triangle between the crank, drive shaft and main shaft for a lighter, more compact transmission. - New Air Intake
Optimised 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 minimise 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. - 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. - Race-Winning Details
The YZ450F boasts a wide range of top-spec details including 1-1/8-inch aluminium tapered handlebars, new compact PVC handlebar pad, new lightweight throttle cable, wide footpegs with new lightweight aluminium alloy brackets, a quick-adjust clutch perch, stylish blue rims and a lightweight gold drive chain with new YZ450F-specific chain guide.
