LOL.Maybe You should've.Think it through a little better next time.
A dyno with speed measured on it tells the owner nothing. Unless that dyno has superfans on it that can replicate a 120mph wind head-on into the bike, that top speed would only be relevant if you could ride the bike in a vacumn.
Remember, wind resistance is exponential and once you're over 50mph, you'll need exponentially more hp for each additional mph to push through even greater wind resistance. That's why mph on a dyno graph are completely irrelevant at anything other than very low speeds.

Just subtract the mph from the air resistance calculation.
I remember this one guy bragging about the 170mph dyno run his Ford F150 HD edition truck did. What a goofball.
