YMA is pleased to announce an all-new benchmark-setting YZ450F motocross weapon for 2023 that's lighter, slimmer, sharper and faster.
Fresh off consecutive US motocross and supercross titles as well as being the current AUS MX title holder, Yamaha took the class-leading YZ450F and made it even better. We made it more powerful, lighter, slimmer, with enhanced overall stability and with more agility than ever. Introducing the all-new 2023 Yamaha YZ450F...because the best don’t rest.
Three models that scored updates last model year continue with those great features while the rest of the VictorYZone range also continues on its winning ways with fresh new MY23 graphics.
Because when winning is the game, you need to stay in the VictorYZone...
Designed to Dominate
YZ450F is the bike to beat on MX tracks around the globe. In the hands of Dylan Ferrandis and Eli Tomac, this model has led the field in both MX and SX in the US. In Europe Jeremy Seewer and Glenn Coldenhoff have shown the winning potential while in AUS the YZ450F is both the reigning ProMX Champ thanks to Luke Clout and current 2022 series leader courtesy Aaron Tanti.
Our engineers have taken that winning package and made it lighter, more compact and boosted power across the entire rev range. The all-new 450cc engine maintains the YZ450F's exceptional pulling power and renowned ease-of-use, while boosting the rev limit by 500 rpm for even more top-end go.
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.
For MY23 YZ450F is specced with an entirely new engine featuring revised air intake, lightweight camshaft design, new cylinder head with optimised ports and bigger intake valves, lightweight cylinder and piston, superior cooling system, lighter balancer with fewer vibes, lightweight generator system, a new ECU, plus new timing chain and tensioner.
The revisions don’t stop there because there’s a new lightweight clutch design that uses a conical spring with separate push lever for less bulk and better action, while the five speed transmission is now both stronger and lighter.
Excellent cornering performance and stability are achieved by reducing overall weight. The new lightweight chassis is more compact to give a more ergonomic riding position with optimised rigidity.
Front fork settings are also optimised while a new wiring harness, lightweight footpeg brackets, new rear axle and rear brake and integrated handlebar switch all shave weight.
To increase usability for riders, the smartphone operated power tuner app now comes with more intuitive functions.
To further cement the M23 YZ450F’s position at the top of the tree, new styling is specified with a slim shroud, shorter front mudguard, extended front fork protectors and new flexible riding position. Price is set at $14,499 inc GST ready to ride, availability is from December 2022. Get ready to dominate...
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. 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.
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.
New Yamaha Power Tuner App
Like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner App is revised to be even 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.
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.
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.
Revised Suspension with Toolless Fork Adjustment
The YZ450F's front KYB forks now feature a new hand operated compression clicker for simple, toolless adjustments. To match the new chassis, fork damping characteristics are tuned to optimise traction and bump absorption. KYB rear suspension now features newly revised internal valving to complement the new chassis.
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 narrower and radiator shrouds to be slimmer.
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.
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 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.
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 narrower 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.
