Revised KYB suspension including updated rear linkage and new settings front and rear. The rear shock lever ratio is revised for added traction and stability. Plus a lighter spring rate is specced for the rear shock and new delta-shaped piston shims in the fork for enhanced stability, traction and a more planted feel. The front fork also features tool-free compression clickers for easy adjustment.
Featuring a reversed cylinder head layout, forged aluminium piston, titanium valves, lightened crank assembly and dry sump lubrication, the YZ450F's advanced DOHC four-stroke engine is light, compact and world renowned for its incredibly broad pulling power across the entire rev range.
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.
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. Features include an intuitive “Simple Tuning” slide bar for quick engine mapping adjustments, Traction and Launch Control tuning, lap timer, along with helpful engine and suspension tuning guides. Best of all, it's free-of-charge.
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.
Optimised intake path draws air from under the side covers and seat allowing for a lighter, slimmer and more compact shroud area. The airbox cover sits low and is narrow, surrounded by the slim radiator shrouds.
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.
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.
The YZ450F boasts a wide range of top-spec details including aluminium tapered handlebars, compact PVC handlebar pad, lightweight throttle cable, wide footpegs with lightweight aluminium alloy brackets, a quick-adjust clutch perch and seamless seat.
