Description
Overview
The RAM-B-309-1U is a motorcycle brake/clutch reservoir ball base that adds a RAM B Size 1" ball to compatible handlebar control clamps. It provides a clean mounting point for building a RAM Mounts motorcycle setup without requiring a separate handlebar clamp.
This base is commonly used to mount phones, GPS units, cameras, and other small devices when paired with a compatible RAM B Size socket arm and device holder. It is a practical option when handlebar space is limited or when a centered control-clamp mounting location is preferred.
