Well my "weekend" bike is my Tbird and my commuter is a Yamaha FJR 1300. I expect everyone to jump on this and say "well you don't want a car tire on your FJR" and I probably agree. I have Pilot 2s on the Yamaha now and I think they will last longer than the stock. My Tbird Metzeler need changing at 7500 miles and that's the bike I would more likely consider car tire for. I have to maintain my son's bike too (I know he needs to do it but he's in college etc.) and all this maintenance adds up to a headache!
