Well I finally took the 650 down to alleghany down in pennsylvania. I got to open it up real good. The 650 is down right fast. I lined up against my buddies stock 96 kx125 and I had no problem in the drag race. I'm sure he could beat me in the long run, but I had him in the take off because I had more traction and a better start. I was even suprised at how well the 650 jumps. It soaks up the jumps easily. Very impressed. As long as this machine holds up and doesn't have any major problems, I'll be keeping this machine for a long while!
