I've had other bikes, including a Screamin' Eagle Road King, and everyone resulted in some bum pain after a while. Recently, I got a BMW C 650 GT. After an hour I had a sore bum, even though the seat was not bad. I was looking into Corbin or other seats and happen to see a picture of an AIRHAWK R on another 650. Curious, I looked it up and recognized it is the same material my friend who needs a wheelchair uses. I had to try it! It performs so much better than expected, I really can't believe it. I had a 6 hour ride today, NO PAIN at ALL! Also, I ride in the Sacramento area and seat sweat was a significant issue. The air flow of the R has eliminated this problem as well. I'll never ride without an AIRHAWK again!
