I've got them on my R100s/5. I like them pretty well. I think for the money, they're great, but I have Ikon's on another bike, and I like them better. The Yss's ride pretty hard, and I weigh just under 200#. If I were 160, I don't think I'd like them very much!
I wouldn't bring her home to Mama, but Mama ain't home tonight.
