Yamaha YZ450FSP

Class-leading four-stroke performance wrapped in iconic heritage YZ style, the YZ450F 50th Anniversary Edition draws its inspiration from 1990s-era Yamaha two-stroke motocrossers to honor 50 years of Yamaha off-road innovation. Building on its best-in-class performance, the 2024 YZ450F boasts exceptional power and sharp handling in a compact, lightweight package that makes fast riders even faster.

Featuring a reversed cylinder head layout, forged aluminum piston, titanium valves, lightened crank assembly and dry sump lubrication, the 2024 YZ450F's advanced DOHC four-stroke engine is light, compact and world renowned for its incredibly broad pulling power across the entire rev range.

And like having factory team support in your pocket, Yamaha's groundbreaking Power Tuner 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.

Lightweight Aluminium Beam Frame

Lightweight Aluminium Beam Frame

The precisely tuned 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.

Strong, Lightweight Wheels

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.

Class-Leading Suspension

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 YZ450F's highly refined chassis. Newly revised internal valving works in combination with the frame and body to improve traction and increase cornering performance. Additionally, the front fork features a hand operated compression damping adjuster for simple, toolless adjustments.

Optimised Air Intake

Optimised 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

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.

Compact Five-Speed Transmission

Compact Five-Speed Transmission

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.
