i've seen a pred or two out on the trial but never seen one race. the 525 my dealer has is still sitting in the dealership. i raced both of my buddies with built 450's. if and when they beat me, its only by half of quad and thats it. I'm only running a pipe, programmer and air filter while both 450's have piston, cam, port/polish and exhaust. if i ever decide to go ahead and get a 11:1 piston, megacycle x1 cam and a trail port job, its a wrap for both of them.
