My classic has the original seat which I'm pretty sure is the one you posted. Im 6'4" 275 and i hate it. It is fairly thin, and ican feel the pan through the foam, which starts to hurt after about 30min. A lighter guy may not have this problem. I seem to remember reading that if its a popular factory seat, so it may just be me.
I just ordered a gel roadster seat on ebay. I wanted a little more height, and more padding. Hopefully it will do the trick.
