RAM MOUNTS Fork Stem Mount for 12–38mm Fork Tubes — B-Size 1" Ball, Vibration-Resistant

RAM MOUNTS Motorcycle Fork Stem Mount secures electronics and accessories to fork stems 12mm–38mm with a B-size 1" rubber ball for adjustable, vibration-resistant positioning.

This fork stem mount from RAM MOUNTS is engineered to attach accessories—GPS units, phones, cameras, or small lights—directly to a motorcycle's fork stem. Built from powder-coated, marine-grade aluminum and designed to fit inside the cylindrical bore of fork stems, the mount uses RAM's B-size 1" rubber ball so you can connect it to any B-size double-socket arm for flexible routing and precise sightlines.

Will this fit my motorcycle's fork stem diameter?

The mount is designed to clamp within the cylindrical bore of fork stems and accommodates tube diameters from 12mm to 38mm. Fit depends on bore size and stem geometry, so verify your fork stem inner bore or outer tube diameter before ordering.

• Compatible range: 12mm to 38mm fork tubes
• Installs into the cylindrical bore area of standard fork stems
• Works on many sport, touring, and standard motorcycle forks
• Measure the bore or outer tube to confirm fit

How adjustable and stable is the mounting system?

The included B-size 1" RAM rubber ball pairs with any B-size double-socket arm to give near-infinite adjustment for angle and orientation. The ball-and-socket interface holds position under vibration while allowing quick reorientation when needed.
