I found that Dunlap K-81's Stuck like glue and lasted longer. I was getting 5000 miles on a rear and 10,000 on my front. With the K-81's got me 10,000 on rear and 20,000 on the front. of course that is if you ain't doing burn-outs all the time. I just put K-81's on a 1982 Gold Wing that I have. And it too handle's great.
