And for everyone saying 'ST tires have all the grip you'll ever need'...it's not just about grip, which btw may be decent but certainly isn't near as good as a good sport tire. I can break loose the rear PR3 on my Tuono at lean wayyyyy easier than I did the Rosso Corsas that preceded them; the front tire feels likes its squirming like jello at times compared to the Corsas and the touring tire profile is just not conducive to the geometry of a sport bike. When I ride my T with PR3s back to back with my RSV4 with Supercorsas, the difference in tire performance is very noticeable. I/you may be able to 'get by' fine on PR3s, but they are not near equivalent to the riding experience of a good sport tire.
