ok I will be the first to admit defeat. I went to pass a stinking diesel ford f-350 pickup truck and let me tell you there was something special about his set-up. I think he anticapated that I was about to pass, we were going about 80 to start with, then I pulled around to pass, we were side by side, the typical 80 to about 110 in (you all know how fast that happens) and this sucker was still right beside me. I gave up, I don't really think that he could have beat my bike but he beat (me). I do not really like high speed/I just love the acceleraation.
