I installed one using a Ram Mount Ball Base and a Female Ram Mount Ball screwed to a chrome cup holder.
The nice thing about using the Ram Mount parts is the holder can be swung out if the passenger opts to swing out the arm rests. My suggestion is to use at least the 3" Ram Connector, the short 2" just doesn't quite cut it for me for clearance if the arm rests are swung out.

I just added the arm rests on my 2021 F3L and have been searching for a drink holder. This is a great idea thanks!
For our 2020 RT-L, somewhere on Amazon I purchased a Kuryakyn Spyder passenger drink holder, part # 1785. Now that number doesn't show on the Kuryakin website, so I don't know if it's still available, or what model it originally fit. It will squeeze onto the passenger handrail, behind the armrest support - about the only spot I could get it to work.
Wife's happy with it, all that matters.DSC04022.jpg
