Japanese Bike Mirrors

Metric cruisers and many Japanese bikes have a 10mm mirror thread. Harley-Davidson mirrors have a different thread size to metric mirrors. This means you need to choose mirrors with a 10mm thread specifically made for metric cruisers or an adaptor to convert Harley mirrors to your larger thread size. All these mirrors have a M10 (10mm) thread. Be careful if you own a Yamaha, as these need specific mirrors or a suitable adaptor for the right hand side, which has an anti-clockwise thread.
