I tried the extensions anyway, and while I found that I didn’t need the extra width, I did find another benefit. Like other OEs using teardrop-shaped mirrors, Indian puts the pointy end outboard. That’s annoying because the outboard edge of the mirror is where I most need to see. I want the wide end outboard. Pivoting the heads around just moves the mirrors inboard, making your shoulders block them. Slater’s extensions allow me to pivot the heads and regain the width. Installation takes about five minutes and requires just a 17mm wrench. If you want the warning text on the mirrors (“Riders in mirror are uglier than they appear” or whatever) to be upright, just swap the mirror heads before reinstalling them.
