I just installed a Kruzer Kaddy on my 06 RKC. Website: http://www.kruzerkaddy.net/index.html It is a very nice product and looks like it was made for the bike. I have the chrome one. I did have one complaint about the design though. When it is loaded with a liquid that is taller than about 2 inches above the top of the cup holder it gets real tippy. I took a chance and called the manufacture of the holder and they immediately offered to send me a set of rubber grommets to stop it from being tippy. What great customer service and friendly people. Just thought I 'd pass along my story in case you are thinking of this product.

I took a piece of thin safety wire and wrapped it around where the holder hooked to the mount with the holder in place. That fixed mine from tipping over. They need to make that groove a lot thinner than what it is.
