I run nothing but Bridgestones on front of mine. My opinion Dunlops are dangerous. They have little to no grip on tar snakes and on a wet road they are worst. As for the rear I am dark sider and prefer a Pirelli on the back.
I found the Dunlops on my Valkyrie to be very slippery on the wet roads, I really preferred the Avons. On my B I have had such excellent mileage and traction from the Bridgestones that I find no reason to switch. Getting about 17 - 18 thousand out of the back and 22 thousand out of the front. Could probably get a 1000 or so more out of each, but I don't like to wear to low on the tread.
