i hear ya, i love to ride also and dont care if i win or lose. As for the 400 keeping up with the 250r, you must be able to ride the hell out of that 400 because every time i see those two quads race the 250r wins. But who knows i guess it all comes down to who knows how to ride there atv at its highest potential. And as for the 355cc crankin out 40 hp im not sure about that but ill get back to you on monday because im going out of town for the weekend and im already late.
