Well after implanting a 3/8 inch thick gel pad and covering it with a 1/8 inch foam before putting the original seat cover back on, I decided to take the thumper for a 60mile round trip ride to Lake George. To keep up with traffic I was driving at between 65-75mph. It was like sitting on a TENS unit at that speed. (transcutaneous electrical nerve stimulater) after awhile my cheeks were numb. The foot begs were vibrating so well that if it was not for wearing sneakers and the pegs being made of rubber, my feet would have fallen off the pegs.
