Obviously Gary and Mike could not get a speed on every machine in every race. A job well done.
Top speed is a result of horsepower, aerodynamics and correct gearing.
At Daytona, top speed is important and correct gearing with the changing wind conditions becomes very technical. In most classes the fastest recorded machines finished in front. Slowest was a F-125 motorcycle going 64 mph. Sounds easy until you try it. I think we could have had it pretty well under control as long as there were 10 or fewer bikes in a race.
