Bone stock bike, never had the chance to put it on a Dyno so I have no idea what rear wheel HP I have. I was on a slight down grade (1%) had a decent tail wind and about 1/8 of a tank of gas. I wound her out to about 15k in top gear(red line is 15.5k) and I had 174mph indicated. but you have to remember that the faster you go. Especially above 120mph the more your speedometer is off. So guess I was only going around 160's.
