I purchased an air-hawk (small square) seat designed for the passenger seat but I use it on the main one. It worked great on my 8000 km trip to the grand canyon and back. It raises your seat very little because they recommend only 1/2 inch or so of air in the pad. This allows your body to move and conform without losing the feel of actually sitting on your motorcycle. I would heartily recommend it especially if you are planning any 500+ mile days or have any butt issues

. Only issue I had was that it gets wet in the rain as the pad cover will soak it up and get your seat wet if you don't have rain gear on. First rate product. I think I would get with the bigger square pad for the main seat next time, though mine works okay.
