After purchasing the 20 oz Butler for myself, it was decided to go with the 34 oz for the passenger. I have the Honda armrests installed therefore installation required the 'Butler No Armrest' kit.

I think it is a bit expensive and I do not care for how large it appears hanging off the side of the motorcycle. These reasons deduct one star from my rating.

It was easy to install and seems sturdy. These cups are convenient and will make other 'non-Butler cup' riders envious. Just ask anyone that has spilled or had their drink blown out of an inferior cup.

Installed for the wife lost the cup on first trip. You have to keep a level in cup so it doesn't fly out. I talked with Rita at Glass Act and she send me a replacement cup at no cost. They run a great company and will buy again for the next bike. Had them on all four wings but first time for the passenger they are worth the cost. Just wish that they came in different colors.

Loved my Driver's Drink Butler so much last year, that before we left on our recent 4300 mile trip to South Dakota in June, I installed the Passenger Drink Butler with chrome bracket to our 2006 Navi Goldwing. Since we have the new Rivco Armrests (which tilt up instead of outward), this allow the cup to stay level, & out of the way, when opening the rear truck. Bracket quality was excellent & looks good even when the cup & holder are removed. Well worth the money!

Ordered one for the driver (me) and the passenger one. Only had time to put on one so mama comes first. She absolutely loves it, will mount mine soon. The cup stays in the holder well and no spillage due to bumps and the likes.

I bought the drivers Butler Drink 34oz cup for me but since the wife needed it more I could either buy the passenger drink cup our see if I could use mine on hers. Since I already had a Kuryakyn passanger arm rest with swing out cup holder it became a breeze to replace the Butler holder. So if you want to save some money you can use the drivers holder. Converting it back to the drivers handlebars is easy for those long rides without the wife if needed. It fits perfect. As always Wingstuff wss fast on getting the Butler Cup to our house.
