The problem with most of those is that your arms are going to be in the way. You'll be constantly moving your arms to see the mirrors.

 

I used Joker Machine's bar end mirrors. I did one on each side, left side is a breeze, right side install is a little more involved because you have to deal with the throttle functionality. Visibility using them I would say is fair. The ones I have are the smaller size, they offer larger ones.

Sorry for the somewhat low quality picture.



Motogadget has a similar barend mirror as well. If I were to do it again I would probably go with theirs, only because I like the way they look a little better.

 

I’m a former Sportster 48 owner. It takes a little while to figure out their “sweet spot”, but I never had to move my arms out of the way on my old bike.

I’ve thought about bar end mirrors, and I’m still not sure about how they look.
