The law says you are supposed to have a set on your motorcycle. So, make them functional in size, but not too big to the point where they would destroy the good looks of your bars/controls.
The head-size of these Diamond-Head mirrors measures only 5” wide x 2 ½” high, which means they still work the way they are supposed to. They are sold with 2 different size stems: 5 ¾” Slayer style or 3 ½” and 4 ½” radius style, with all of the necessary chrome hardware included for installation
Made from chrome-plated die-cast aluminum, Sold in pairs with prices starting at $109.95.
Contact your local Drag Specialties dealer.
I think that they are the 2nd most important functional item that you can have .First is a Air Horn and 2nd is a good set of Vibration free Mirrors with a functional size as these are. Price is right and they look great…………..Winner.
Convex? if not, worthless.
