Frequently Asked Questions

What can I mount to this base?

Any RAM accessory arm or holder with a 1-inch ball connector — phones, GPS units, GoPros, cup holders, and more.

Will the vibration from my motorcycle damage the rubber ball?

No — the Nitrile rubber ball is engineered to absorb and dampen vibration, protecting both the ball and your mounted device.

Is this weatherproof?

The marine-grade aluminum and stainless steel hardware resist corrosion. The Nitrile rubber ball is weather-resistant for outdoor use.

How is it mounted to my bike?

The 3.5-inch bolt circle allows bolting to your motorcycle frame, handlebar clamps, or other solid mounting points. Hardware and exact mounting method depend on your model.

Does it come with a lifetime warranty?
