I used the K60s on my F8 for my trip to Mongolia and Siberia this year... can't say I liked how they handled on the road, especially in the wet. I think I got one puncture on the front K60 in Siberia from a spoke after the rim tape got displaced and the bead was very easy to break on this with just my hands or standing on the tyre wall. I got one puncture in the rear K60 in Mongolia and I broke the bead easily with the sidestand. However, when I got back to the UK I put some Conti Trail attacks on, now that I was back onto tarmac, but on this occasion the rear K60 bead was a bitch to break even with the sidestand. I did eventually manage to do it after considerable effort. For off road (dual purpose), I still prefer the TKC80...I just wish I could get more miles out of one.
