The Kayaba Upgrade Kit improves the behaviour of the front fork through increased performance and feedback.
Maintains the flex of the original inner and outertubes that has been designed for KTM & Husqvarna frames.

The KYB feel combines perfectly with the KTM & Husqvarna character - giving it a very smooth feel - eliminating the harshness while building up a progressive damping profile toward the end of the stroke.
