don't let air forks scare you I been using them since 2013 , we have our settings down pat , beside you can change them to spring as race tech have spring conversion for showa and soon kyb but we work on gold valving them which helps especially the mid valve , they skf have new internal seal heads design to reduce friction on the showa and race tech also have new bottoming cones as well for them , I also tried the 2015 kx450 forks on the std k5 and they were a improvement , the 16 450 forks are better again , plus they are so light. as soon I find a set of air forks I will be bolting on my 01 250 /500 , as bladder forks are rubbish tip material.
