At first I hated it because it is so stinkin' firm. However now that it is broke in, I think it is great! I have done over 500 miles, mostly interstate, in one day and very little complaint from down there!
Wife thinks it is great too since she can see over my head better! The only bd thing is it does not work real well with Harley accessories like the detachable backrest (works but not great!).
Second best purchase...first was real shocks from progrssive!
