Mirror Block Off Plates are machined from solid blocks of billet aluminum alloy. The primary function of a mirror cap is to eliminate turbulence caused by wind flowing over non-homogeneous surfaces; these covers help streamline the bike's外观, improving aesthetics. They prevent unsightly and non-functional holes from remaining after mirrors are removed. These plates are designed to block off holes after removing stock mirrors. Easy to install with no modifications required to your motorcycle.
