3D Round Custom Motorcycle Mirrors are direct bolt on replacements for the stock Harley Davidson mirrors or can be installed on any custom chopper, bobber and most custom bikes. Mirror head and stem are one piece: the advantage of using one piece motorcycle mirrors is that on custom bikes with high vibrations the mirrors will stay firm in the position you set them. Obviously if your handlebars vibrate, the chrome billet mirrors will vibrate with them. Mirror glass adjusts pressing on glass surface, with an internal system similar to the one used on car’s mirrors. These custom motorcycle mirrors feature a very distinctive design and perfectly match our New 3D Motorcycle Hand Controls, 3D Motorcycle Hand Controls, 3D Custom Motorcycle Grips and 3D Custom Forward Controls. We also offer black custom motorcycle mirrors for customers that prefer the “dark look”. They can be used as metric motorcycle mirrors when installed with our Mirror Adapter for Metric Cruisers. Sold individually.
