Here is a HOT program to down-load.

TopSpeed is a program I started in the 80's when I was Road Racing heavily.

It was originally designed to give me the speed of the bike in all of the gears.

It has over the years grown to include 4 stroke exhaust design, engine calculations,

lobe center calculations and power calculations. It is FREE so feel free to distribute

it to anyone who wants it.

This program is for W indows XP and above.
