What have y'all tried and what works for a handlebar cup holder on the Rushmore?
I want it on the left side of the bars and I will be putting a 20oz RTIC cup in it. (same as 20oz Yeti)

 

Cup holders are a lot like seats and oil, everyone has their preference.
I like the Kuryakin one

I like it for a few reasons, it's chrome!
It comes with the stainless mug
It will also hold a 20oz cup from gas stations and fast food places
And I adapted my Butler mug and ring to it, ( the Butler is the ugliest but the best )
And with the Butler mug I can also leave the mug empty and drop a bottle of water into the mug.

Very versatile and looks good when not in use.

 

This is what I have. Works great, especially the swivel. I Chew so I use it for a 'toon. Could be a little deeper but never had a spill or bump-out.

I went with the Kruzer Kaddy #500, chrome, has different foam insert liners, and bolts to the control mounting holes (they supply new longer bolts) for either the right or left side.
Got it on amazon for around $35 or so.

I have the same one. I also bent the bracket so it will stay 100% upright.

 

I have the Kruzer Kaddy mounted on the left...it's nice but wants to tip to the left/right with a full drink in it. Never an issue on my '10 SG but not crazy about it with my '14 Limited.

 

I have had the same Cup holder for 18 years.. unfortunately it's a 1 of a kind and I think I will keep her

 

I have the Butler. Its big and ugly, but works well. Its so dang ugly, that I only mount it when traveling though. Did I mention that its ugly?

 

Kruzer Kaddy, put a washer on it where cup mounts, stays put

 

I like this one. Do you have it mounted to the controls, or on the bar? I'm thinking of using a bar clamp on the crash guard....
