I too have a difficult time believing the speed in the first video wasn't somehow rigged.

With the original Dunlop D-87 (185-60) tires I was observing that the speedometer would read about 3 mph high at an indicated 60 mph and about 10 or 12 mph high at an indicated 120 mph (actual speed closer to 110). Currently, I am running 195-60/14 AVS-I and the errors observed are less. Basically, the error goes up geometrically. I am not sure why.

A 195-60 tire is taller than a 185-60 tire. First number being tire width in millimeters, second being the sidewall heigth divided by the width. So keeping the same sidewall ratio with a wider tire makes the tire diameter larger, because the sidewall is taller.
So this guy you quoted had a speedometer reading higher than actual speed, got taller tires, and now his speedometer is more correct.

The bottom line is, when I was traveling around 155 as measured by my hinny-dyno, the terrain was wizzing by at a greater rate than shown in the video.
As for the other stuff, feel free to read all about it and you can give us all math lesson. http://www.se-r.net/electrical/top_speed_speedo.html

either way, anyone going 100 on a bike is suicidal IMO. I dont like doing it in a CAR, much less with nothing around me. But then again ive never driven a moto. At least the guy had a helmet...not that it would help at 100+
