It only takes a slight tweak for the Touring to out perform a stock Roadster but it takes a fair bit to make the roadster into a two up Touring motorcycle ,full screen,footboards, spotlights, back rest ,panniers , luggage rack ,Full size Gel pillion seat ect, a stock touring has enough power/torque to satisfy most people but just knowing there are 40 odd more horses in there that are easily released is too tempting, and you have the best of both worlds
