If you're tired of seeing your own shoulders in your rearview mirrors, then these are for you! This pair of mirror extenders screw into the original mirror mount on your motorcycle heandlebars, providing a spacer between the base of the rearview mirror and the motorcycle's original mirror mount.
The height of the part itself is 38mm. The actual displacement will vary depending on the angle that the extenders are mounted onto the bike.
This is for left/right threaded M10 mirrors only - 30mm.
