    Don't know.... From what I have seen and heard over the years and talking to a couple people, most people think mine should be right around a very low 50 horsepower. You see what I got below.... Me personally, I don't know... But I do know it's quick. My first two motos this year against modded 450r's and yfz's I took the wholeshot in the first moto and second out of the whole in the second moto... Not trying to be smart and make someone mad, but that's the honest truth. Got it on video even...
