Horsepower is a measurement of doing a certain amount of work in a known period of time. And there is more than one way to measure engine HP depending on how and where it is loaded.

(http://en.wikipedia.org/wiki/Horsepower)

I found a way to measure how much HP your bike is producing, taking your weight into account.
Type (copy) the web address below into your browser.
Putting in the weight of your bike + your weight and the speed you that you can reach in 1/4 mile, it will calulate how much HP your bike is producing.
(You can change the units to pounds and miles/hour)

If you reach top speed before 1/4 mile then the formula would have to change.

I swear to God if we had tricycles there would be trash talk.With these things it's not so much a displacement thing as it is the fact that i weigh 50 to 60 lbs more than you thats gonna kill my chances.
