Right at about 11k miles on my CB500X RR. I was over 5k when I left for the Continental Divide Trail. Probably another 1k pavement miles left, but I've had a plug (put in while on the CDT) come out twice in the last few weeks. The new set arrived last Friday, I just have to figure out how/where/when I'm going to have them put on. High marks from me, and I beat the hell out of them both on and off pavement.
