Just installed the excedra 130 front tire, have had the excedra max rear tire for about a year. As others have posted, the improvement in handling with this combo is amazing, feels like a different bike, a much lighter bike. I had a Dunlop 404 on the front that was pretty worn out and causing a significant slow speed wobble. With the new excedra the wobble is completely gone.
It is funny that the m109r's are going from excedra to metz's and we are going from metz's to excedra's. I would say that it is just anti "stockism" but the Rocket is a much better bike with the exedra's, I hope the 109'rs are getting equal improvement with the metz's.
I doubt I will ever put another metz on the Rocket, everything else I have put on has been better than the metz i.e. avon's, bridgies, and dunlops.
