I have used the TKC80's on many dual sports and love them. I immediately put them on my WR250R and was impressed. I use stock pressure on the street and for off road rides go to 15 front and 15 rear. They work great on both the street and off road in all conditions. I have since put on a Pirelli MT43 on the back to try it out. Not sure of it yet. It sticks like glue in the hard dirt and rock areas, but not sure on loose sand and mud. Time will tell. The TKC 80 is good everywhere.
