I have track bodywork (Amour Bodies Supersport) on my bike but I was using my stock seat on my 07 GSXR 600. I wanted to change out the seat because I slide around entirely too much on the stock seat. I bought the seat pad, took off the seat cover and cushion and simply stuck the seat pad to the stock seat pan. IMMEDIATELY I could tell the difference. It kept me in place even under extremely hard braking which meant I wouldn't tire as quickly. So if you are thinking about buying this product GO FOR IT!!!!!!!!
If you are going to do what I did and reuse the stock seat pan, use additional adhesive to hold the pad in place.
