BikeMaster American Mirror Yamaha 10mm - Each - Chrome - 601121

The BikeMaster American Mirror for Yamaha with 10mm thread — Chrome (Part #601121) is a classic-styled replacement motorcycle mirror designed specifically for Yamaha bikes that use a 10mm stem thread. Whether you're refreshing worn-out OEM mirrors or upgrading to a bolder, American-style look, this chrome mirror delivers a deep, high-polished finish and extra-heavy construction that stands out on cruisers, standards, and vintage Yamaha builds alike.

Key Features & Benefits

• Deep, High-Polished Chrome Finish: The mirror features a genuine high-polish chrome surface that adds a premium, show-quality shine to your Yamaha — a noticeable step up from dull or pitted stock mirrors.
• Extra-Heavy Construction: Built with extra-heavy materials, this mirror is designed to resist vibration and hold its adjusted position mile after mile, reducing the constant re-adjusting that plagues lighter aftermarket mirrors.
• Universal Stem Fits Left or Right Side: The universal stem design means a single mirror can be mounted on either the left or right handlebar — giving you flexibility when replacing just one side or building a custom setup.
• 10mm Yamaha-Specific Thread: Engineered with the correct 10mm thread size for Yamaha motorcycles, so you get a secure, rattle-free fit without adapters or modifications.
• Reverse Right Thread (Yamaha Standard): The 10mm Yamaha fitment uses reverse (right-hand) threading as is standard for the right-side mirror on Yamaha bikes, ensuring it threads in correctly and stays tight during riding.
• Sold Individually: Priced and sold as a single mirror, so you only buy what you need — handy when replacing one damaged mirror without buying a full pair.
