Found the OEM seat made me feel as though I was sliding forwards all the time. Replaced it with a Corbin which is a lot more comfortable but perhaps a bit wide if the feet are having to go down at all. Negative aspects are that it's ridiculously heavy and not that well made for the money- all the bracket bolts were crossthreaded, with some stripped threads, and although I complained to Corbin they didn't bother to reply. I bought a Sargent for a H***a sportbike (RC51) I also ride, and the seat beautifully made and very light, and as far as comfort goes I've not even thought about it, so it must be good.
