My prostocks are strong enough for riding two up however depending on your seat they do not work well in some cases. on the 04 and up two part seats there is a gap of around 1.5 inches at the end of the passenger pad as the fender slopes down. I can however make a custom passenger pad pan that you can have an uphoslstere set up for you. the stock 02/03 seats fit quite well. If not I also make a stock style widened fender for 280's that we could bob if you want to keep one of the later passenger pad set ups. or you could keep it stock and use your stock tail light assembly as well.
