Murph Kit bar risers, SW-Motech GPS mount with $100 Chinese GPS, Sato Racing frame sliders (for use as another place to rest my feet), Tall VStream windscreen for when I have to go to Iowa and smash bugs. Run a 55 rear tire, too. Added a Tusk 12v plug in the place inside the upper fairing that makes sense, using the factory aux power leads. Only mechanical modification is drilling a bunch of holes in the clutch drum so it doesn't squawk between periods of hard riding. If you corner hard a lot, you don't need the holes.
