I don't know what happened to my first post but I am doing it again. We have just finished our first of many Can-am DS450 MX builds. The bike was built by TM Motorsports in west palm beach florida. It has DG nerf's, bumpers and skid plate. (thanks Jr.) Epic a arms and axle, Fox racing shox and a ported head, pipe, filter and intake. We will be at the dyno testing all of the engine combo's we have. So stay tuned for some real numbers.
