I've run TKC 80s on my Super Tenere for a couple of winters and got about 4500 miles out of rear. So when the OEM Metzeler rear wore out on my XT660R in about 4000 miles (along with TWO punctures!) eventualy stuck with what I know and put as set of TKCs on. I havn't done much off-road with them but on road find they inspire far more confidence, more so in very poor road condition (mud, lose gravel, ice etc.). If they do break traction they recover grip in a very predictable way.
