Prob only said that because it was actually closer than he liked it to be. I mean realistically it's not double the power or double the RPMs on a 400. Reminds me of the first time I got on a 660 Raptor That was supposed to be bored up to something I don't know. I've never been on one and everyone who talked about them hyped them up but when I got on it it's just kind of reminded me of a KX 125 that I grew up riding. Maybe a little faster.
