These bikes were designed to carry a rider of the same weight as the number of cc's at 50 mph.

For example: a 125cc Model 125 or Hummer would carry a 125 lb teenager at 50 mph. A Model 165 or Super 10 would carry the same passenger faster, or a heavier passenger the same speed. Same for the 175cc Pacer, Scat and Bobcat.

The 14th Law of Thermocouples gives us this equation:

Number of cc's
----------------- * 50 = top speed
Rider weight (lbs)

Or, in layman's terms, skinny people go faster than lard-butts.

The effect of headwinds or tailwinds on top speed is non-liner, and increases with wind velocity. A 20 mph tail wind will add about 10% (2 mph) to the top speed. A hurricane with 100 mph winds may add 50% of wind velocity - you may find yourself flying along at 100 mph! Or 0 mph, depending on which direction you're going.

The effect of hills on top speed is well known. The length of the hill and the angle of inclination (or declination) combined determine the effect on top speed, but this has something to do with the cosine of theta, which makes it an intractable problem as far as I'm concerned.

Leaning down to minimize wind resistance certainly has an effect. Just look at the guys on their Ninja bikes - they're bent over double in a highly unnatural position. But is does work - they can go from home to chiropractor at upwards of 300 mph!

Good night, and good luck.


What top speed of super 10?
