2 coat painting is pretty much obvious. Sporty handling is probably more the seating position such as supersport. While rubber mounts on both the frame could mean that it will have a lower seat rail, runs a little smoother, is a bit heavier but more power which should off balance the weight. While optimum rigdity is probably pointing to the steel frame which offers an ideal rigidity balance in the longitudinal, lateral, and torsional directions, using the engine as a stressed member.
