The BIKE IT Handlebar Mirror Extender is designed for motorcycle riders struggling with obstructed rear visibility due to their shoulders or forearms. By providing 40mm of horizontal and 27mm of vertical extension, this accessory significantly improves your field of vision, making lane changes and traffic monitoring safer. While it is an essential safety upgrade, note that it is specifically engineered for mirrors using the 10mm Yamaha thread standard, so verify your motorcycle's compatibility before installation.

FAQs

Will this fit all motorcycles?

No, this specific part is designed only for motorcycles that utilize the 10mm Yamaha thread pattern.

Does it add significant weight to the handlebar?

The extenders are lightweight and will not cause noticeable changes to your motorcycle's steering feel.

Can I install these myself?

Yes, installation requires only basic hand tools, such as an adjustable wrench or the appropriately sized open-ended spanner.

Will I need to replace my mirrors?

No, these extenders are designed to work with your existing factory or aftermarket mirrors, provided they have 10mm stems.

Is the black finish durable?

The finish is designed to be weather-resistant and match standard factory components, standing up well to typical outdoor exposure.

Troubleshooting

Mirror vibrates at high speeds

Ensure both the extender-to-handlebar and mirror-to-extender connections are tightened firmly with an open-ended wrench.

The threads do not match my mirror

Verify if your motorcycle is a standard Yamaha model; if the bike uses a universal thread (M10x1.25), you may need the 'Standard Thread' version instead.

Pros and Cons

Pros

  • Blends seamlessly with stock motorcycle parts
  • Simple to install with basic hand tools
  • Improves safety during lane changes

  • Not compatible with non-Yamaha standard mirror threads

Setup, Compatibility & Care

Installation is straightforward but requires attention to the specific thread type. Always ensure your motorcycle uses a 10mm Yamaha thread (typically identifiable by the reverse thread on one side).

  1. Loosen your existing mirror lock nut.
  2. Remove the current mirror by unscrewing it clockwise or counter-clockwise depending on the side.
  3. Screw the BIKE IT extender onto the handlebar mount, ensuring it is tightened securely.
  4. Attach your original mirror into the top of the extender.
  5. Adjust for your preferred viewing angle and tighten the lock nuts.

Regular maintenance involves checking that the extender remains tight every few thousand miles or during routine oil changes, as engine vibration can loosen threaded components over time.
