I used them on my Concours 14, a really heavy bike, and had 5K on them when I sold it with about half life left in them. This is using daily in the Texas heat. They are the most awesome tires I have ever used in over 30 years of riding! Awesome feedback in all conditions, no warmup time, smooth quiet ride on the slab. When I get my buell it will either these or the PR3 as the first order of business!
