These parts were designed to allow you to convert your WP 4CS, AER or Xplor fork into a “works” performing kyb fork. This is the same fork that everyone has been raving about on the yamaha for years! These parts need to be installed by a skilled suspension tuner. You will need to source kyb cartridges or you can purchase here.
For fitment with AER or Xplor fork you must send in your lugs for modification.
