The Holy Grail of tires for the old enduros. I found a small stash of 3.25 x 19 Universal Trials tires and they are pretty dirty, but they are highly sought after pieces. You will need to do some cleanup, but the all appear very pliable. Don’t wait to buy one of these. Good for Honda SL350 K0, K1 and Yamaha Enduros DT & RT.
