Thanks Capn' Bob,
You make a very rational argument. I have been loyal to Pilot Power 2CT since I switched from Dunlop 205s, then D207s a few years ago. After trying the PPs I was hooked. I run them on all my sport bikes- Hayabusa, RC51 and Superhawk. The handling is only slightly better than the Dunlops, but the tire life, especially the rear is at least 2X if not 3X. But you have motivated me to try the Pirelli's on my new (used) Concours once the Pilot Road 2CT's wear out. Thanks for your thoughtful and intelligent comments. Until I have tried them I will not know if they are better.
