I installed the RAM-mount cupholder to an accessory bar across the top of the dash, not to the handlebar bolts. But the same idea. It works pretty well, but I've learned a few things:
1. When empty the cupholder rotates quite a bit around the screw mount due to the turbulence behind the windscreen. That has eroded the hole in the plastic that mounts the thing. I'm going to drill the plastic out and install a metal sleeve, and also put a piece of elastic on the bottom that will allow the cup holder to swivel some but not rotate.
2. The cupholder doesn't retain things inside of it very well, especially light things like empty soda cans or coffee cups. Couple that with the swinging (see #1 above) and bumps in the road and I've lost a few things by the roadside. Remedy: put the empty in your jacket pocket, or install an elastic mesh over the top of it (also a work in progress).
3. Grande Frappuccino in a Vente cup, no whip, gives enough headspace that it won't slop out. Likewise with coffee.
4. At Starbucks, use the large Frap straw to fill the sipper hole in the coffee top to reduce slopping. Also see #3 regarding headspace.
5. Anything slopping down onto the tank top makes a mess and in places that aren't easy to wipe up.
6. You will need a modular helmet with tilt-up chin to drink properly. Full-face with a fixed chin bar won't work with containers, even with straws. But they do work well with CamelBak-type with flexible hoses and pinch valves.
7. Re: #6, you're not supposed to ride with the chin bar on a modular helmet raised.
8. Cruise control is a wonderful thing when drinking from a container.
9. After you install the cupholder, people will see it and think you're nuts.
