I'll jump in this post for a sec....I like Michelins, dad was a Michelin dealer....so!
Anyhow last year I got some very good milleage out of a set of PRs, they however wore a little flat from heat and slabbing. I am switching to PR2 this year, according to all the reports I have seen, very good milleage and excellent in the rain.
For the "sportier" riders a combination of rear PR2/front Power apparently works pretty good!
What I haven't figured out is if all the PR2 are "Load rated B" or if they do make them in "Load rating A"......! None of the online suppliers, or even Michelin, seems to mention that, and yes it is important as BMW themselves recommend "B" on them heavy bikes.
Any info on that?
But here is their website so you can go say Hi to Bibendum.....!
