Multi Moto Shootout WinnerDirt Rider, and shootout winner. Huge power and industry-best suspension, even better for 2017.Top Features 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. 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. 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. 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.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.
