Hello, I just purchased a white 821 and absolutely love the bike. I ordered CRG LS bar end mirrors and would like to order Rhinomoto bar end mirror adapters but I don't know the inside diameter of the factory handlebars. I am currently away from my bike so I was hoping someone might have that measurement handy. I want to order the adapters asap and Rhinomoto doesn't know what size I need. Thanks again for the help.

I installed some SATO Racing Bar Ends. They were designed for bars between 14-18 MM and they fit no problem. The plastic cap measures just over 15mm that comes stock with the bike so a figure of about 16mm is about right given the taper. I hope this info helps.
