They are not the same, but you only need a pair of reducer sleeves to adapt klx110 All Balls tapers to a pitster/long crf style stem. I made a set in an afternoon on the lathe and they worked great..
What I meant by that, was that the klx and the crf head sets are different. I also have a Medina Front end (as-01's) and they are much different then the gpx/pitster forks but the solution to mount them on a klx is the same for sure ..
