The Hindle looks sick...
I know what you mean about the weight though. My bike already had the Leo Vinces on it, but the original owner turned the box in with the original exhaust cans, so the dealer gave them to me. Jesus H Christ.... I picked up that box and was not ready for that kind of weight. I think I almost dropped it on my foot.
I can only imagine what that kind of weight would have done to the handling and acceleration...
