I have the HB on my Stornello. It went on easy. The dealer swapped in the Euro stand for the US stand, although as others have noted, that is needed for the OEM but not the HB. My one gripe is that the foot deployment arm sticks out about 3 inches further than you would like as there is no left muffler. A welder friend is going to cut a piece out over the winter when I'm not riding.
