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.

NEW FIVE-SPEED TRANSMISSION

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.

RACE-WINNING DETAILS

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 YZ450Fspecific chain guide.

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.

REVISED SUSPENSION WITH TOOLLESS ADJUSTMENT

REVISED SUSPENSION WITH TOOLLESS 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

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.

LIGHTWEIGHT ALUMINIUM BEAM FRAME

LIGHTWEIGHT ALUMINIUM 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 POWER TUNER APP

NEW 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.

ALL-NEW 450CC ENGINE

ALL-NEW 450CC 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.
