NO MORE NUMB BUTT!; The Airhawk 2 Medium Cruiser is made from a polyurethane and measures 14" x 14" at its longest and widest point. It works best for shorter touring and cruising bikes. It is a great fit on the Harley Road King, Ultra Classic, Street Glide, Road Glide, and Honda GL1800 Gold Wing. If your not sure if this is the best model for your bike you can always pull out the tape measure. It does not have to cover the entire seat but should cover where you sit.
