I got a set on Power Pilots today (190/50/17 rear) and took my bike out to scrub in the tires before my track day. First, the tires warm up quick, have great grip even before getting scrubbed in. Good feed back and perdictable. By my second run through the loop at Red Rock ( a hot spot for sportbikes here in Vegas that has alot of 25mph tight twisties) I had gotten full lean on the tires with very little slipage. After a little more miles on the tires ( I only got 30 on them now) thses tires are going to stick like glue. I have run the Diablo Corsas before and I think that the power pilots are a touch better. Just though I would let you guys know how they perform.
