It mounts to the clamp for the clutch reservoir you simply remove the two screws and use supplied spacers and bolts and mount the cup holder there. Chrome is excellent and looks great on the bike. Only reason I took it off is because I didn't find myself using it.
Can't believe you didn't use it even if not for its intended purpose. Makes an excellent cell phone holder, smokes, etc. My cell rides in there perfectly and I see when I get a call and don't hear it. Of course I don't answer while driving, but can pull over if its someone important.
I got an iPhone 6s and it doesn't fit. The most I used it for was holding my glasses while putting my helmet on. If I'm long distance where I would need a drink while riding I am mostly with my wife which means I am stopping every hour and a half anyway so might as well just drink then.
What did you replace the windshield Chrome with? I have the exact same color Limited and was thinking on going with the Chrome with Amber lights, but not sure how it would look against the fairing paint.
