Review on Universal Fit Adjustable Mirror Set for Motorcycles and Scooters - 8mm Reverse Thread - Flat Black (1411C) by Robert Lee

These inexpensive plastic mirrors were just what I was looking for. 8mm, good price, they fit and work very well. They are lighter than stock mirrors and provide better visibility (stock mirrors were round). They fit my bike (2007 BMW F650GS) and look like they are stock. Plastic pads on the base of the mirror and mounting threads are of high quality and work perfectly. The reverse thread on the left mirror is also a good idea (some mirrors don't have it, and wind and vibration will loosen the mirror). The only problem is that the mirror mount doesn't offer enough resistance for off-road or rough driving, so the mirrors move when pushed and there's no way to adjust the tension.
