ENGINE

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.

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 & Updated Launch Control
The 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 now features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.

New Compact Lightweight Clutch
The all-new clutch design replaces the coil springs of the previous model with a new disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smoother engagement and excellent feel. A new clutch cover employs a stylish geometric design that helps minimize scratching and lends a premium look.

New Air Intake
Optimized 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 more narrow and radiator shrouds to be slimmer.

CHASSIS

All-New Aluminum Bilateral Beam Frame

A completely redesigned aluminum 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 Compact Lightweight Clutch

The all-new clutch design replaces the coil springs of the previous model with a new disc spring and integrates primary gear and basket into a single steel unit. The result is a more compact, lightweight and durable assembly which yields smoother engagement and excellent feel. A new clutch cover employs a stylish geometric design that helps minimize scratching and lends a premium look.

Slimmer Body & Improved Ergonomics

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 more narrow 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.

Updated Rear Brake

Rear brake feel is improved by reducing the rigidity of the brake hose, providing a wider range of control at the pedal.

Revised Suspension with Toolless Fork Adjustment

The YZ450F's front fork now features a new hand operated compression clicker for simple, toolless adjustments. To match the new chassis, front fork and rear shock damping characteristics are tuned to optimize traction and bump absorption.

ADDITIONAL FEATURES

XC-Focused Details 
The YZ450FX includes a range of cross-country-specific upgrades compared to the YZ450F motocrosser including a composite engine guard, 18-inch rear wheel, sealed O-ring chain, fuel level warning indicator and a folding aluminum kickstand.

Adjustable Handlebar Mounts 
The 4-position adjustable handlebar clamps are rubber mounted to improve comfort, reduce handlebar vibration and allow riders to adjust the bar position while the oversize 1-1/8-inch handlebar is strong but lightweight.

Embedded Graphics 
Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage.
