Most of the Metzler problems were the 880"s.The place I have my tires mounted in Reno NV has installed 100's of Metzler 888's without a problem and I have a set on my 13 F6B with about 9 thousand trouble free miles.Stick well in all conditions and are wearing pretty nice as I am a big dude at 385lbs and could see 15 thousand out of the rear.Original Bridgestones gave me about 10 thousand miles to wear bars.Only bitch I have on the Metzlers is they have become a little whinny in the lean.Might try the E4's next time as many here have reported good things about them.Ran Avons on a few other Goldwings and while they stick like glue to the road they wear fast!
