TOP FEATURES
1. Innovative Engine Design
The revolutionary rearward-slanted-cylinder design of the YZ450F™ allows for a straight down-draft intake with a symmetrical port layout for smooth controllable power delivery throughout the RPM range. This engine design also achieves unmatched mass centralization, for light and nimble handling.
2. GYTR® Power Tuner Ready
Accessory GYTR Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons, as well as monitor engine diagnostic codes.
3. Launch Control System (LCS)
LCS optimizes engine output for quicker, smoother race starts every time, boosting controllability out of the gate.
4. Ideal Frame Rigidity Balance
The bilateral beam frame features a carefully chosen combination of forged, cast and extruded aluminum pieces, when combined produce superior cornering traction and unmatched lightweight handling.
5. Class- Leading Suspension
Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption, for race-winning handling performance. The linkage type rear suspension features a KYB® shock with ideal damping characteristics to match the compact chassis.
FEATURES & BENEFITS
NEW FOR 2017:
Simplified Servicing
Redesigned air cleaner over helps prevent contact with the quick-release quarter-turn Dzus® air box fasteners, providing tool-less access to the air filter that’s positioned at the front of the bike avoiding roost from the rear wheel.
New Rear Brake Rotor
Updated rear brake rotor material that has better heat resistance providing better durability and braking feel.
New Dunlop® MX3S® tires
For 2017, the YZ450F features soft-to-intermediate terrain tires, the Dunlop® MX3S®.
New Graphics
Stylish new graphics treatment brings the YZ450F even closer to that pure factory racer look, that are molded directly into the plastic, for extended durability, resisting both peeling and damage.
ENGINE
Advanced Engine Design
The revolutionary rearward-slanted-cylinder design of the YZ450F moves the engine and rotational mass of the cams towards the center of the bike to provide class-leading mass centralization. Concentrating the motorcycle’s key components—engine, fuel tank and exhaust system—toward the center of the motorcycle achieving light and nimble on track handling performance. Additionally, providing a straight shot, downdraft intake and a symmetrical port layout for smooth controllable power delivery throughout the RPM range.
GYTR® Power Tuner Ready
Accessory GYTR® Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons, as well as monitor engine diagnostic codes.
Launch Control System (LCS)
LCS optimizes engine output for quicker, smoother race starts every time, boosting controllability out of the gate allowing you to get to the first turn first.
Advanced Fuel Injection
The engine breathes through a 44mm throttle body fed by a high pressure electric pump to ensure optimum fuel atomization and power for a wide range of riding conditions, instantly adjusting the air/fuel mixture for changing altitude or temperature.
Wraparound Rear-Positioned Exhaust Layout
An innovative exhaust pipe design is adopted to increase mass centralization and improve power development characteristics. This layout moves the rear end of the exhaust pipe farther forward and enables a muffler position close to the center of the mass.
CHASSIS/SUSPENSION
Bilateral Beam Aluminum Frame
Yamaha’s renowned aluminum bilateral beam frame that features overall dimensions that are roughly the same as the frame of the YZ250F. This gives the YZ450F a compact chassis that provides the most instinctive handling in the 450 motocross class.
Class-Leading Suspension
Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping provides exceptional balance between handling and bump absorption, for race-winning handling performance. The linkage type rear suspension features a KYB® shock with ideal damping characteristics to match the compact chassis.
270mm Front Brake
Large 270mm front disc brake coupled with aggressive pad material offers outstanding braking performance and machine control, with exceptional stopping power and controllability. Out back, a new, more heat-resistant rear rotor boosts brake durability.
ADDITIONAL FEATURES
Adjustable Handlebar Mounts
The 4-position adjustable handlebar mounts are rubber mounted to improve comfort and reduce handlebar vibration.
Embedded Graphics
Yamaha’s unique embedded graphics are built into the bodywork for extended durability, resisting both peeling and damage, with new styling for 2017.
