Default Re: 200 MPH Harley-Davidson

If I fire a cow out of a giant cannon, can I be recorded in the history books for the fastest cow?
This statement is false.

Default Re: Do-it-yourself drag calculation

1) The result is consistent with reality within about 5% either way in several speed tests on modified motorcycles and right in line with MotoGP bikes that have exceeded 200 MPH.

2) 5% is all you can expect given the difficulty of reaching and measuring top speed; repeated runs tend to vary that much.

3) Bikes are out of boundary layer flow and into turbulent flow from about 5 mph till the edge of the speed of sound. The method holds quite well over that range.
