Thanks for the advice, guys. Up until now I've been very pleased with Dunlop's. I've had a few Metzler's and Pirelli's on other bikes, but for whatever reason not too interested in Michelin's. The bike had PR4GT's on it when I got it, and while they were worn-but not worn out, I couldn't wait to replace them. As the saying goes, YMMV.I have not been a Michelin PR fan since PR2 but the PR5 looks different from 3 and 4, looks a lot like the Pilot Power RS I run on my track bike. So far n0 complaints except for the high price. If I get 12000 miles I will be happy. But of course the RT does not have the power or weight of the Concours.
