When I visit NYC on my V7C I always cover it and cable lock the wheels to the frame, and pray. I think it is a must to have some cylinder protectors and a good idea to have saddlebags because when the cars park so many knock the motorcycles over. They couldn't care less if they damage your bike. I am not sure if a centerstand would be better than the sidestand. Might be a good idea to remove the mirrors. If your building has a door man, persuade him to keep an eye on it too
