This one is 14 x 14 measure the seat and see if it will fit.....I have one for my wife for the Rune and she loves it and could not ride long distance w/o it......The trick to a air hawk is...very low air pressure, it looks like a carton on eggs...when aired correctly it will look under inflated...to check if you squeeze " one " of the egg thingys flat the rest stand up and appear full..hope this helps....then again the Russell seat is the answer!!!
Thanks for link! My research has turned up that 18x18 is the size needed for the Goldwing. I think I will give this a shot before I go the custom route...
