I assure you the top speed of a stock 400ex is not 72 mph. However, this is any endless battle and I'm not going any further. Been there, done that!

I have ran mine and it will only go 64.8mph bone stock i have since put a K&N on it along with white bros rev kit im not sure if that helped or not ive heard the fastest is 65 which is faster than you or any one can take one down through the woods it will go as fast through a corner as you got the nuts to push the throttle.

I can get 72mph on mine too. Well, my uncle got 72 on radar with his a few time, but most of the time he would get 70 or 71. I can go a little bit faster than him so I'm probably 73 or 74. I don't want to start a fight with everyone, but I'm just posting my results. When I use to have a 300EX I could get anywhere from 59-61. Depending on wind, temp, etc. All of these reading were done with a radar and on an a paved airstrip. Plus I have my fenders cut and ducking out of the wind gives you a few more mph. On dirt is would be slower especially if you don't duck out of the wind. Anyway, these are my finding anyway.
