Our all-new Fork Adjusters for the ’23 YZ450F are machined from aircraft grade aluminum and replace the stock plastic adjusters. We use a 4-flute design and made them slightly taller to allow for easier adjustments with a more solid detent. Factory look with magnesium color and laser etched +/- markings for reference. The 4-flute design is much easier to use with or without gloves on. It is also easier to gain access to the fork bleeder screw due to the smaller size adjuster.
