I have tried the Ultimate seat and sent it back. I have a Gel Full Cut seat, hard like a rock, but better than stock. I have owned 2 Corbins in the past on my sport bikes, very hard and was worse than the stock Busa seat, but better than the stock ZX9 seat.
So I ordered a Russell All Day Long seat and it is here.
For those of you who do not know about these seats:
They have you fill out a form with your measurements
They request pictures of you flat footed on the bike and with your feet on the pegs in your riding position
They will rework the seat at no cost if you are not comfortable....twice
That being said they are ugly in my opinion, but at age 41 I am starting to favor function over form.
Here are the pictures on and off the bike. My opinion after a quick 5 mile ride is my butt died and went to Heaven. It is incredibly comfortable and will do a long ride soon to confirm.
