Front Forks removed from a 1999 Kawasaki KX250 2 Stroke Dirtbike. NOT all years use the same diameter, you may have issue fitting forks into triple tree if incorrect year/diameter. These are the KYB forks you will see marked K312-L and K312-R on the bottom. They have 46mm chrome tubes on the bottom. Where they clamp into the triple tree is 54.9mm (Upper) and 58.4mm (Lower).
Used Condition, WITH ISSUES - Please Read. There are some scuffs on the upper sections that go through the triple tree, you can see these in the photos. Those scuffs would just be a cosmetic issue. However, you can see light streaking on the lower chrome sections when held in the right light - nothing to catch a finger nail in but you can see it. Typically this is caused by dirt and dirty oil. The streaking is shown in the last two photos. No damage where the wheel and brake mounts except for one small bolt thread that is cross-threaded (I'm pointing to it in one photo) - Just where the plastic fork guard bolts on. The seals will no doubt need replacing and the oil changed. I have no idea when these forks were last serviced, so new bushings are always a good idea when changing seals.
