I'm not 100% sure, but I believe that 500+ weight limit is the Gross Vehicle Weight Limit of the bike + the rider and cargo. The carrying capacity should be 300+ lbs.
My Super 8 150 says weight limit of about 330 lbs, with a GVWL of 500 and something lbs.
Either way, if you're 200 lbs, it should be fine. My 150 still flirts with 60+ mph with my 230 lb butt on it.
