The review would be higher but they are not the easiest to install. Sidewalls are quite stiff. That aside these things are rototillers. I had to stay way back from my son because I kept getting pelted. I have only 5 hrs in the trails and a day on the track so my durability is yet to be seen. I can say that I did have dunlops on both yz450s and the difference was night and day as far as traction and steering ability. The yz450 is noted to be tough to turn and this is a different bike with these tires. Does the yz still needs more help hes but the tires were a good start.
