Happy with my Corbin
All in all, I'm happy with my Corbin. I thought it was too hard at first, but now that it's broken in it feels fine. It's about five times more comfortable than the stocker, and it fixes the problem of sliding into the tank and crushing your 'nads. It also allows one to slide back about an extra inch versus the stock seat, which makes longer rides more comfortable. I found the stock seat so bad that I literally couldn't ride ten miles without being in severe discomfort.
Be prepared for the extra weight that comes with the Corbin. It's easily ten pounds heavier than the stock seat, and that weight is located up high on the bike. You will probably notice the difference in how the bike feels. Good luck, and happy riding.
