Review on 🏍️ Motorcycle Bike Mirror Mount Risers Extenders Adapters Rearview Side Mirror Adapter CNC Aluminum 10mm Right & Left Thread - Ideal for Yamaha Models by Doug Hawkins

The Royal Enfield has a right hand thread mirror and a left hand thread mirror so that's exactly what I need. There were no obvious machine marks on the extensions and the satin black finish was pretty good. They moved the mirrors out just far enough to provide a good view of the rear and blind spots, while not half filling the mirrors with elbows and shoulders. They came with two 10mm stainless steel mounting screws (left and right) and two lock washers. I'm taking a star off my rating because the lock washers are too big to fit into the recesses in the extensions so I had to use blue threadlock to secure them in place. Otherwise they are great and I can only recommend them.
