Guys, I'm at work...away from the bike...Can someone measure the diameter of the headlight of the 919? I'm looking to put this http://www.lamin-x.com in optic blue on my headlight. But they just emailed me and they don't have a pre-cut fab made yet and they need the measurements. I put it on my 07 Audi A4 and it looks awesome, now I want to do it to my bike. Anyone?
