I'm very close to purchasing a 2015 RGS (currently have an 07 road king), but one thing concerns me. I ride 2 up much of the time. I weigh 230 and the wife weighs about 130. The specs indicate that travel on the rear shock is only 2.1 inches. I'm very concerned that the stock will either bottom out or take the bumps hard depending on the setting. I know that the probable answer is to go aftermarket, but I'm already upgrading the windshield and the seat and that's about all I want to spend at this time. My question is, does the stock shock handle the weight and bumps, or will I absolutely have to upgrade? Thanks.
