Kewig Motorcycle Fork-Stem Phone Mount — Triple-Tree Mount 12–25.4mm, 4-Corner Lock & One-Hand Operation

This fork-stem phone mount fits directly into the center hole of your motorcycle’s triple tree (fork stem) to deliver a compact, low-profile mounting point for navigation, ride tracking, and quick access. Designed for riders who want their phone visible and secure without bulky handlebar clamps, the Kewig mount uses stainless-steel components and soft-touch materials to protect your device on varied road surfaces.

How does this mount attach to my motorcycle’s fork stem?

The mount installs into the triple tree center hole (fork stem) and uses interchangeable spacers to fit tubes between 12 mm and 25.4 mm in diameter. You choose the small or large spacer before fitting the ball base, and the base requires a minimum 38 mm tube depth for a secure hold.

• Fits tube/shaft hole diameter: 12–25.4 mm
• Included spacers: small (12–18.5 mm) and large (18.5–25.4 mm)
• Minimum supported tube depth: 38 mm
• Do not install if fork stem hole has a protruding lip

Will my phone stay safe on rough roads?

The Kewig mount clamps your phone at four corners using stainless-steel telescopic arms combined with TPU and silicone padding to absorb vibration and prevent scratching. The design keeps the camera recessed so it isn’t squeezed or damaged while riding.

• Four-corner wrap keeps phone steady on bumpy surfaces
• TPU ball joint and silicone pads reduce vibration and abrasion
• Stainless-steel arms provide durable, rigid support
• Non-contact camera area prevents lens pressure and scuffs

How easy is it to insert and remove my phone while riding?

This mount offers one-push automatic locking and a quick-release mechanism so you can install or remove your phone with one hand in about a second. A 360° rotation joint allows fast switching between portrait and landscape for maps, ride cameras, or music controls.

• One-handed insertion and one-push auto-lock
• Quick release for fast removal at stops
• Full 360° rotation for portrait and landscape viewing
• Compatible with phone thickness under 16 mm

Which phones will this mount support and what should I check before buying?

Kewig’s fork stem mount supports most smartphones with screen sizes from 4.0" to 6.9" and phone thicknesses under 16 mm. Before purchasing, measure your fork stem hole diameter and verify minimum depth; select the appropriate spacer included in the package.

• Phone size compatibility: 4.0"–6.9" screens
• Maximum phone thickness: 16 mm
• Measure fork stem hole diameter and tube depth before installation
• Do not use if the fork stem hole has a lip or obstructing edge

Who is this for: Riders who prefer a low-profile, center-mounted phone location—especially those using navigation, recording rides, or needing a stable screen view without handlebar clutter. It’s suited to sport bikes, street bikes, and custom builds where the triple tree has a clean center hole and at least 38 mm of depth. If you want strong metal construction, vibration protection, quick one-handed access, and adjustable fit for a range of tube diameters and phone sizes, the Kewig Motorcycle Fork Stem Phone Mount is built for that use case.
