I have been tabulating some information to derive at a formula to calculate the rear wheel horsepower of a motorcycle on a Dynojet Dynamometer based off of the MPH ran at a dragstrip. I know there are a ton of variables, but this is only a "rough guide".
The intent of this post is not to blow holes in this style of calculating, but more to find out if the numbers work for others. We could "finesse" these numbers with some good input from others who have known good runs on their bikes...see if it works for you and your replies would be grateful.
Formula: Top Speed divided by 230 = "Y".
Then Y X Y X Y X bike and rider weight = H.P.
