No, good observation, Those mirrors are Buell Blast mirrors. They list for like
$20 bucks a piece. They are the same metric thread as the 919. What I did was put the mirrors in a vice, and bent them down. The metal used in those mirrors are weak enough to bend, but strong enough to take it. Now due to the stress the paint will crack. So you will have to sand, and re-paint. What you end up with are 3 inch round mirrors that you can see clearly behind you without the illusion of convex bar end mirrors. I think the bar ends look better, but my preference in traffic are these.
