I got some pretty respectable mileage out of the stock rear with fairly good grip too. When the rear was shot, I replaced the pair with a set of good Pirelli Super Corsica race take-offs. I just don't use my Busa in a way that I can really feel the advantage of the Pirelli's. I never got them warm enough and I just don't have hardly any curvy roads around here anyway. So, the rear Pirelli is shot now, and I'm going back to the stock Bridgestone's. I've seen polls done by other Busa owners and the Bridgestones seem to be a good mix between mileage and grip. I do plenty of distance riding and that's what I'm going to be using in the future.
