I had one on my bike that Newt gave me at the GA rally last year but it fell off sometime after the NY rally and before our Oct Dragon Run. I know I went over a speedbump on my way back from NY and the bell scraped it but it stayed on the bike. That may have damaged it though - I had it hanging on the bottom part of the frame (underneath the right foot peg). One day I noticed that the loop was still there but the bell part had fallen off somewhere. The bell didn't keep a gremlin from pulling one of the leads off ignition coils but I'd put another on if it was given to me.
