I have ran this tire on a few different bikes of my own (05 yz250f, 08 RMZ 450, and 08 KTM 250XC) and some of my riding buddies have tried it. Here'w what I think ... In soft terrain it's a great tire hooks up like a soft terrain tire should cleans out easily. Now that being said if you run the tire on any kind of hard pack and you ride aggressively it is going to show wear very quickly. Some of the more expensive tires cross over between hard and soft terrain better but for the money I can't complain. Thanks Motosport for offering an affordable product that provides adequate performance for us weekend warriors!!
