I rode the Corbin on my RSV for 3 years. It's hard and more of a saddle than a seat. I've done several cross country trips, on stock and Corbin. All of them were painful after 75 miles. I recently changed to a RDL after my wife started riding with me and the Corbin was just to hard for her. The RDL is a huge improvement. I can ride from one tank to the next without stopping to let the blood flow back into the rear. The RDL is the best long distance seat I've ridden by far. If you ride or plan to ride long distance, you will be pleased with RDL. It looks different, but it's beautiful to your .....um:whistling: rear end!!!
