Put me in the minority, I guess, but I don't care for bar end mirrors. My '83 came with a pair and they were the first items removed and tossed. New grips followed to replace those butchered for the bar end install.
I like my scoots to have the narrow look so the bar ends didn't do it for me, visually. No pun intended. I have aftermarket black, rectangular mirrors with short stalks. I attached 1.50-inch diameter wide-angle stickies to both mirrors and can see all around.
Being a bit paranoid, I still turn my head and use the Mk-1 eyeball to confirm my six is clear.
