1. Good quality and pretty sticky
I have to say when I bought my 15 R1 I was going to swap the tires out right away for the Pirelli Supercorsa. However, after touching the compound and about 100 miles. I was VERY impressed with how these stuck to the road. Dont get me wrong, I still like the supercorsa from Pirelli the best as far as turn in and confidence goes. But surprisingly this isn't just another junky battleaxe from Bridgestone. They really stepped up their game and released a good road/track day tire. Would I race in CCS with these. No. But they do their job for about 1,000 hard street miles and one track day. I will buy another rear until the front is done.
