Ok now, wait for something crazy simple:
Take Bike+rider weight, Divide by 0-60 time, Divide the result by 2 again for horsepower.
from the Chuck Hawks review of the stock bonneville, they give the bike weight as 499lbs. say the driver's 176, a 0-60 time of 5 seconds gives you
675/5/2= 65 hp
It's not right but it's surprisingly close for such a simple formula.
For the Rocket, 900 lbs, 3 seconds, it gives 900/3/2=150 hp
Ok it's optimistic but hey, don't we all want a few more HP? The reason this gives 150 hp vs the 142 i got in an earlier post is that the last divide by two should really be a bit more - maybe 2.1. If you use that you get more like 142 and 62 hp.
