MULTI MOTO SHOOTOUT WINNER

Last year’s dominant shootout-winner adds many performance-enhancing refinements for 2017 to its huge power and industry-best suspension.

Features may include:
  • 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.
