I have a brand new never been mounted Pirelli Diablo Corsa III rear tire in a 180/55/17 The distributor sent me the wrong size as I need a 190/55/17 ON MY gsxr 1000 Because of the 6" wide rim. im willing to let it go for $150 cash. so all you 600's, 750's and such who want an extremely grippy tire that is getting phenominal reviews get in here!
