I am thinking that over rev is going to have to be classified as usable power range, which its still not at the rpm's he is trying to justify. I cant think of anyone thats building a twin cylinder banshee motor thats actually pulling 14k rpm in a mx race, drag race, or play bike. I ride with Patriot Racing, twister, Rooster, Trinity, ILR, Redline, and RSR bikes. I even ride with some of the owners of those companies themselves.
