This seat was used 1time on a trip with both of us and then my she bought her own Harley. I went to back to a solo seat. It is in excellent/like new condition and paid close to $500 for it. The driver seat is approx.17" in width and passenger 16" and nice and thick with back support to driver. It fits models with the front mount on the seat pointing towards the fuel tank. Does not have the slot...
