Mine is a one piece seat. My wife complains about rides longer then an hour too. I did find a good thing to get rid of a lot of the vibrations in the bike, hence making it smoother/more comfortable... Put a new exhaust on it that has more back pressure then what I had one, HUGE difference, plus less sound for long rides is always a plus. Previous owner put a supertrap on it with the open end (only to be used for racing genereally) so it was a straight through exhaust. I put on another supertrap with 8 disks and the closed cap, world of difference!
