I was lucky enough to pick up a kdx with USD forks already installed, however I'm blanking on what bike/year the guy pulled the forks from. I need to do the fork seals and am hoping somebody can give me some insight on which model I have. I dont have the tube diameter right now but I can grab a set of calipers tomorrow and update this thread.
