My Q2's are about gone,and they have been great. My problem with the them is I don't want to change tires in 2000 miles,so I'm looking to try some Michelin Power Pures,but have seen some post on a local site,easttnriders.com, about some people not liking this tire on heavier bikes. Looking for some feedback here on the Pure's on Busa's. Thanks Peyton
