New 2023 Yamaha YZ450F

Fresh off consecutive pro Motocross & Supercross titles, Yamaha took the class-leading YZ450F and made it even better—more powerful, lighter, slimmer, with enhanced overall stability and more agility than ever! Introducing the all-new 2023 Yamaha YZ450F, because the best don’t rest.

Features may include:

• All-New 450cc Four-Stroke Engine

The new 2023 YZ450Fs 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.

• 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 YZ450Fs 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.

• Race-Winning Details

The YZ450F boasts a wide range of top-spec details including 1-1/8-inch aluminum tapered handlebars, new compact PVC handlebar pad, new lightweight throttle cable, wide footpegs with new lightweight aluminum alloy brackets, a quick-adjust clutch perch, stylish blue rims and a lightweight gold drive chain with new YZ450F-specific chain guide.
