Annie ran them on her F650GS, including across the Top of the World last year in some very sloppy conditions. They are a good comprimise between something like a TKC at one end and a tourance at the other. With about 2500 miles on them her rear has squared off a bit: I'm told that is at least in part due to running too high a pressure in them.
