The motorcycle fork stem ball base features a 1'' TPU ball joint attached to an aluminum alloy round plate, designed to fit into the cylindrical or hexagonal bore wall of motorcycle fork stems. Suitable for stem tubes ranging from 12mm to 25.4mm in diameter, this ball base is compatible with RAM MOUNTS' B size double socket arm.

The package includes two sizes of metal spacers: a small size spacer for tubes 12mm to 18.5mm in diameter, and a large size spacer for tubes 18.5mm to 25.4mm in diameter. Users can choose the appropriate spacer based on the tube diameter for installation, but it is not recommended to use two spacers of different sizes simultaneously.

The anti-theft design of the metal motorcycle fork stem base adds extra security to the equipment attached to it. The bolt head has a specially designed screw groove, and the package includes a unique wrench for tightening or loosening the bolt.

Before installation, users are advised to measure the tube diameter and select the correct spacer. The minimum tube depth required is 38mm. The installation process is straightforward: insert the ball base into the motorcycle fork stem tube, and use the included special wrench to tighten the bolt clockwise.

The product offers a range of compatibility options, with the B size 1" TPU ball allowing connection to RAM MOUNTS and BRCOVAN's B size double socket arm.

In summary, the motorcycle fork stem ball base provides a secure and versatile mounting solution for various accessories, with its anti-theft design and easy installation process. Users can choose the appropriate spacer size to fit their specific motorcycle fork stem requirements.
