Last year’s KX-F wasn’t a bad bike, but it did have its shortcomings, namely in the handling and weight departments. When we pulled this bike off the stand, however, we could already tell it was a different machine than its predecessor. On the track, the chassis—1.3 inches slimmer than ’16—gives the rider a more connected feel to the bike, while the overall lighter weight makes it easier to plant the bike wherever you want. Complementing the chassis are revised suspension and linkage settings. And while the settings worked well, removing preload and adding compression in the fork helped the bike remain planted in corners without sacrificing straight-line stability.
