JC, since you mention I do remember reading a thread where you described your bike being a template for our seats. I'd also not seen the Road King seat specifically on the SEEG and was only going by the way it fit on the Road Kings. Again, so as not to make anyone think I'm dis-ing the Corbin SEEG seat on the SEEG, it fits fine. There is a bit more of a gap between the seat and tank than I might like. And that gap varies a bit from one time to anothe when the seat is on or off. But it's actually small and I'm really being pretty picky with it (for what they charge for their seats you earn that privilege).
The Corbin certainly fits better in that same area than did the stock seat. It's just that, like so many things, I wish it were even better than it was.
