This is the close seat with the hole in the back for a Corbin backrest. The guy I bought the bike off of was 5'4". I'm 5'9" and the seat puts me too far forward on the tank. Had another guy interested but backed out. Seat comes with a 2x keys that is needed to remove the seat and the mounting hardware. Here are a few more pic's:How tall are you? Is this a Close Solo Seat or Standard Classic Solo? Does this have the hole in the back to accept a corbin backrest?
