IT'S CORBIN BACK REST. it fits all the corbin seats is my understanding. if your c10 or c14 has a corbin seat, there should be a little hole in the back that the square backrest pole fits into. i listed it for sale here because it is a universal thing for all corbin seats and it's usually half the price of a corbin seat. i've been lurking here a few years wanting a c14 but never found the right deal. i'm riding a new goldwing now...COMFORT for the wife. the more the wife wants to ride, the more i ride
I also have a front and rear alaska leather sheepskin for sale. $50 for both shipped. email to kitesurfer2@comcast.net if interested
