I recently bought this second-hand Corbin Rumble seat. It is in really great condition with no rips and very little noticeable wear. Just a few little indentations here and there in the leather. It has a working backrest and has been freshly treated with Skidmore's leather cream.
As I wrote on the seat review thread (
http://www.motobrick.com/index.php/topic,2121.0.html), the seat is lower than my old Dual Tour and is a little too low for me. I am 6' 1/2" with a 34" inseam.
I am looking to sell or trade. Let me know if you have any questions or want more pics!
