BRCOVAN Metal Fork Stem Mount Base with 1" TPU Ball — Theft-Resistant, Shock-Absorbing

The BRCOVAN Metal Motorcycle Fork Stem Mount Base is a threaded, spacer-fit fork stem adapter with a 1" TPU ball that creates a secure connection for RAM-style arms and accessories.

This fork stem ball base converts a compatible motorcycle fork stem hole into a robust mounting point for GPS, phone holders, action cameras, and other RAM-style accessories. Built from metal with two spacer sizes and a B-size 1" TPU ball, the unit is engineered to fit common stem tube diameters, resist theft with a special bolt groove and wrench, and accept BRCOVAN or other B-size double socket arms for reliable on-bike support.

Will this fit my motorcycle fork stem?

If your fork stem tube has a circular or hexagonal bore between 12 mm and 25.4 mm in diameter this mount is designed to fit. Choose the correct spacer included in the kit to match your tube diameter, and ensure the tube depth is at least 38 mm for secure engagement.

• Compatible bore diameters: 12 mm to 25.4 mm
• Included spacers: small (12–18.5 mm) and large (18.5–25.4 mm)
• Minimum tube depth required: 38 mm
• Not suitable if the stem hole has an inner lip

How do I install the BRCOVAN fork stem base?

Installation is straightforward: select the spacer that matches your tube diameter, insert the ball base into the bore, then tighten the bolt with the special wrench supplied. The bolt head uses a custom groove to help prevent tampering while providing a snug, repeatable clamp inside the stem.

• Step 1: Measure tube diameter and pick correct spacer
• Step 2: Fit spacer around base and insert into stem tube
• Step 3: Use included wrench to tighten bolt clockwise
• Step 4: Attach B-size double socket arm or RAM-compatible accessory

What accessories can I mount to the 1" TPU ball?

The BRCOVAN mount features a B-size 1" TPU ball to accept RAM-style double socket arms and many third-party accessory heads. The TPU ball provides shock-absorbing contact and durable engagement for electronics and light equipment while retaining compatibility with a wide ecosystem of mounts.

• Suitable for phone holders, GPS units, action cameras, and small accessories
• TPU ball helps dampen vibration and protect mount interfaces

How does the anti-theft feature work and why does it matter?

The bolt head is machined with a unique screw groove and the package includes a matching special wrench to tighten or loosen it. This design discourages casual theft or unauthorized removal of your mounted devices while on public roads or overnight stops.

• Special bolt groove resists common tools
• Included exclusive wrench for secure tightening
• Helps prevent easy removal of attached equipment
• Adds peace of mind for urban parking and travel

Who is this for? The BRCOVAN Metal Motorcycle Fork Stem Mount Base suits riders who want a tidy, strong mounting point directly from the fork stem for navigation, communication, or recording devices. It’s ideal for commuter and touring motorcyclists, custom builders, and anyone using RAM-style arms who needs a low-profile, vibration-dampening connection that resists tampering. Before ordering, confirm your stem bore diameter and depth, and avoid use on stems with an inner lip.
