i have got the TKC80 on my Tenere. Good traction off the road as long as the mud is not too deep or too sticky. They don't seem to clean themselfs very well.
On the road i am not too shure about them. Specially in the wet. Strangely the front seems to be holding better than the rear. Needs warming up to be at its best. Does not like low air pressure, rather a notch too high. Does tend to fall into corners. Surprises you at first but trust it.
Good tyre.
