Motorcycle Bar Mount Collars and Screws: Fit Guide

Quick answer

The Peak Design Motorcycle Bar Mount uses three collar sizes and specific screws to fit different handlebar diameters. This guide walks you through selecting the right parts and installing them correctly.

Installation steps

1. Identify your handlebar diameter: Measure your handlebar at the mounting point. Use the collar that matches: small (0.5–0.7 in), medium (0.7–1.0 in), or large (1.0–1.4 in). A common mistake is guessing the size. Always measure with a caliper or ruler.
2. Insert the collar into the mount clamp: Place the correct collar into the groove inside the clamp. Make sure it sits evenly without twisting. If the collar is misaligned, the mount will not tighten evenly.
3. Position the mount on the bar: Place the clamp around the handlebar with the collar in contact. Align the screw holes. Check that the mount is oriented so your phone or camera sits level.
4. Insert and tighten the screws: Use the supplied screws and a 3 mm hex key. Tighten them alternately in small turns until snug. Do not overtighten. Overtightening can strip the threads or crack the collar. Stop when the mount does not rotate.
5. Test the mount before riding: Push and pull the mount firmly. If it moves, tighten the screws a little more. Then attach your phone or camera and check again. A loose mount can damage your device. Re-check after the first ride.
