Here is the front forks that came off of a 1983 Honda XR 80. Had been sitting for a few years. No rust in the chrome tubes where the seal would ever travel. Little bit of rust up higher around the trees as you can see. You could clean that up with a little bit of wd45 and green sos pad.
Seals don't look to be leaking or anything like that. But I would suggest changing the seals while you have them off the bike. Check out my other listings, we have lots of used parts to sell.
