It’s a Corbin classic solo, passenger , and a back rest with studs. It’s a short seat that came off of a road king but I used it on my Electraglide. It’s a great candidate for a recover. There are some cracks on the rider seat and some tearing along the inside of the leg on the left side. Still a good seat with miles to go but if some one needs to have a convertible set up, here are all the pieces. Im looking for $200 shipped CONUS.
