Not ECE approved, for show use only; aluminum; round, diameter 75mm; stem 61mm. Motogadget mo.view mirrors are glassless. CNC machined from aluminum and finish-anodized, but a regular glass lens is not used. Instead the patented mirror surface is convex cut directly from the aluminum. This is done with ultra-precision diamond tools using a special ´flycutting´ procedure after which it is made corrosion and scratch resistant by a special vacuum plasma coating process. Available in regular and handlebar-end mirrors. Left & right side compatible, allows above or below bar end installation and mounts directly onto or into 22mm or 1″ diameter handlebars. Body thickness approx. 4.2mm without ball head. Note: Installation compatible with Motogadget bar end turn signals, the mo-grip and the push button controls mo-switch and mo-switch mini. Note: A bar-end adapter (575353 clamp-on or 575352 clamp-in) is required and sold separately.
