Pirelli Diablo superbike Pro slicks for sale.These are a great track day tire for the hard core enthusiast. They say they don't need warmers (I use them,because I already have them), and they have a wider operating range, so you don't have to be a tuner to get good life out of them. The front is a new 120/70/R17. The rear was used by me at a Thunderhill trackday for six sessions, and looks perfect. It's a 180/55 R17. $240 for the pair. If you have not tried the confidence that Slicks give you, treat your self!
