I bought a set awhile back. Finally mounted them and only had a marginal ride. The rear does act weird as it does not roll over at all. Seemed to grip ok. 2 weeks and we will have a 2 day event. I will know much more then. My first thought was why did I try this, as I already had spare Michilens. They might actually hold a line better. Worst thing is I also had brand new Sidi's on which really hurt my FEEL.
