I have a '96 Thunderbird 900. The seat is awful! After 30 minutes, I'm squirming and my butt is sore. Looks like maybe the PO had short legs? and maybe cut down, kind of "scooped" the foam in the front part of the seat a bit. At any rate, the foam is 22 years old and worn out. Have a Corbin seat, foam is nicely stiff and fairly comfortable, but EWWW! That seat is ugly! Have an "Air Hawk" inflatable strap on pad that works, sorta, but like sitting on a hemorrhoid cushion and adds to seat height making for tippy toes at stops. Asked here elsewhere for suggestions = foam replacement, gel inserts, etc. Not a lot of response. No need to buy a new seat, mine in great condition, but want to make this one better. Any ideas out there?
