There are 3 different ones for the Concours, pictures on the Internet do not show then on the concours, One shows just a seat with buttons on it, another one shows a seat on a Honda ST1300, which is totally different and the third one shows a seat on a Harley Ultra. But I have one that is model K08-13-0291RS. It is on e-bay buy does not have the buttons, which I think is best. Since I don't carry a passenger I can not speak for the comfort on the rear of the seat but it is padded quite well. The front is kind of hard but I think it will break in good. I have only been on 2 rides with it so far. Also the seat does NOT come with any hardware, the hooks on the bottom or the metal piece at the rear that locks it to the bike.
This is the underneath of the seat, (no hardware)
And this is the seat
