I have a 04 R-1 and i'm looking for a Corbin pilot seat.

Good luck ... I have been looking for a reasonable one for about 8 months.

I finally gave in and got one last year. What a difference! The stock seat isn't too bad IMO, but after installing the Corbin, it's like a whole new experience. So comfortable. I would imagine that most people wouldn't get rid of their Corbin unless the bike got totalled. Good luck on the search though.
