Howdy all, I've got to purchase a new rear tyre for my CBR1000 and I'm curious what the difference is, if any at all, between the Pirelli Diablo Rosso Corsa and the Diablo Rosso II? Checking out the Pirelli website and they look much the same. Is one any better then the other and if so in what way? Have to make the purchase today if possible so any help/advice would be great. Thanks a lot.
