On this particular machine no experience, but on other ATV's in the past removal of the sway bar caused the suspension to bottom out when hard cornering. Being an independent rear end, extra weight causes them to squat more. I have heard thru the grapevine that when Artic Cat uses the Kymco machines they put stiffer springs to try to up the weight ratings a little. Can't say if if it is true or not...Don't think I would eve want to remove mine, they are on there for a reason!!
