Joker Machine mirrors are completely CNC machined from billet aluminum, light-weight, strong, and fully adjustable in every direction to fit just about any rider. Solid design reduces vibration and makes for a clearer image. These mirrors can be mounted on the separately available expanding adapters through the ends of most grips by drilling or boring the grip end. Not required for most grips with existing grip end holes. Alternatively, mirrors can be clamped straight onto a 7/8" (22mm) handlebar. Plugs for the standard mirror holes on Harleys are also available. Mirrors, adapters and hole plugs are sold each and can be used left or right.
