Conquer Dirt

Be ahead of the pack when the gate drops with the 2018 YZ450F! The ultimate motocrosser gets a long list of improvements giving it more power; all with the push of a button thanks to the addition of electric start. A newly developed chassis, head-turning style, and an all-new Power Tuner app to fine-tune engine settings right from your Smartphone will have you smiling ear to ear on the podium.

Power

The 449 cc reversed, rear slanting engine receives new cams, valve springs and intake port. New piston with optimized underside ribs makes it lighter and stronger. The result is a higher compression ratio at 12.8:1 delivering a more power, than ever before.



Chassis

To enhance handling and heighten performance on rougher terrain, the bilateral beam frame of the new 2018 YZ450F has been updated to include a straight-line fuel tank rail, re-positioned tension pipes, and newly positioned engine mounts. A lightweight, slimmer air box combined with a new compact fuel tank and seat gives the rider greater freedom to move around while searching for optimal body positioning.

STYLING

Newly designed air ducts, side covers, and more visually aggressive front fender highlight the styling changes for the 2018 YZ450F. Two colour variations are available including the traditional Yamaha Racing Blue and a fresh look on the secondary option with a white, cyan, and black colour palette.


POWER TUNER APP

The new Power Tuner app with expanded functions for the YZ450F not only makes it easy to modify the fuel maps directly from your Smartphone, but also allows you to share settings among your team or with friends. The easy to operate Power Tuner app was developed to work on both Apple and Android platforms and is available as a free download from either the Apple App Store or Google Play.
