Went back to stock. My lady and I two-upped on it for a few trips. I think it's tailored towards guys with 34" inseam (the butt pocked, as Rich states above). Her comfort wasn't much better - then again, we were dong 4-500 mile days. It also adds over an inch to the seat height.
I would like to do a seat mod on the stocker. I do like the way the Corbins look, however.
Put it this way - my ass gets numb from both seats...with the Corbin, it took just a little longer.
