I put these tires on an 04 honda try 400ex. I have had them on there for several years now, and I am quite impressed. I normally ride in the mountains on rough rocky terrain, and I also hit up some good sized mud holes on occasion. No matter what these tires almost always seem to have grip. And when you want the back end to break loose, it does so almost as if on command. They have stood up very well considering the miles i have put on them. Only complaint is that first time out on the new tires, I sprung a leak. I put a little slime in them, and I haven't had a problem since.
