Welcome to the forum. Going on 8,500 mi on my FZ10.just put my third set of tires on. The stock ones were toast at about 3,100mi. Second set were the newer S21 .I got rite at 5,200mi on those. I put the S21's on again. When I retire I'll put something that last longer since I'll be rideing more often. But I like the S21 over the Stock S20's way better.
