All I can say is... HOLY %#@((& I've always been a Michelin Man, but I picked up a set of supercorsas for (get this) FREE! WOW! The Pilot Powers have never let me down, but I was able to get alot more lean (peg draggin like mad with it begging for more) and was absolutely smoking some 600's on the mountain recently. The Corsas have a much better profile, no dive, just smooth all the way down:thumbsup: Only bad thing would be their price, the fact that you have to take the time to get them hot, and their longevity (or lack of). I smoked a new set in 6 days, 1000 miles, no tread left. BUT my goodness were those awesome days! I'm still trying to catch my breath! If you got the Money, try em once! I think you'll like em.
