It's easy to calculate the actual top speed of any moped. Simply take the Riders
weight plus the weight of the moped, divide by the square of the drag coefficient,
then multiply by the Cosine of 30 degrees increased by the maximum exaust port
diameter (metric measure only). With this result, you must then multiply by the
maximum rpm divided by the rear tire radius (English measure only) times 3.1415926
squared. With adequate compensation for temperature, humidity, and altitude above
mean sea level, you should get within a mile or two per hour. But then again you
might not. I just love bench-racing.
