I used to run them front and rear on my Gold Wing and found them to be good tires. The only negative thing is that they seem to cup quite a bit and get noisy whenever the bike is leaned over in a curve. They seemed to handle well. I got an average of 10,000 miles on a set of E3's. I'm running Metzeler's now and I love the way they handle. My wife has Metzelers on her 900LT and absolutely loves them. Me too, and I can't wait til I can replace the stock tire on my 900 Classic with Metzelers.
