Do I need a Vibration Dampener?
We have found that motorbikes with engines of all sizes are capable of producing the high-frequency vibrations that can damage smartphone cameras, so we recommend installing the Vibration Dampener on any Moto Mount, regardless of bike or phone model. You can find the Vibration Dampener here.

Are the Fork Stem Mount, and Fork Stem Mount Pro 360 compatible?
Yes, both the Fork Stem Mount, and Fork Stem Mount Pro are compatible with any of our 360 heads and arms. Since it's part of our 360 range, all components are interchangeable with other 360 parts, allowing you to customise it to suit your needs. You can even build and personalise your setup using our 360 Kit Builder tool, available on our website here.
Why can't I use this if my stem has a lip?
The Quad Lock Fork Stem Mount is designed to be inserted into a smooth, hollow stem tube where the expanding spacers can securely grip the inner walls. If there’s a lip at the top of the stem, it can block the mount from being inserted properly or reduce the available internal depth, which prevents the expansion mechanism from working as intended.
Even if it feels like it’s installed correctly, the clamps may not be making full contact with the inner walls. This can cause the mount to tilt, loosen over time, or even pop out entirely, which risks the customer’s device falling while riding.
