I have a drink holder on the passenger arm rest and not sure what brand but I think Kuryakyn. It is a simply attached to the bottom of the rest and slides out and has a simple bar that prevents your drink from falling through, or so it' s supposed to. The wife got a drink to go the other evening and took a couple drinks and then it was gone. I suppose it fell through the space left between the bracket. I guess my options are........find a good quality metal cup that the top ring fits and won't allow it to fall through or purchase a basket to attach to the holder itself. I guess the 3rd option is to get another drink holder and forget about that one. What are you guys/gals doing?
