Must be an improved version, because so many people have had bad experiences that they call them "Dunflops".
I know the Michelin PR4GTs on the ST1300 are fantastic, so if the Dunlops are better I need to try them.
I test-rode the black ST1300 for a mate the other day and almost ran over the first roundabout, being used to my ST loving the lean and flick. They were original Bridgestones with 7500 (and the front with only 1000 kays left on it). It's a 2010 bike, so they will have gone hard. Horrible feeling!
