This plate and steering stem mount kit is the easiest way to mount any device that has a 4-hole AMPS mounting pattern to motorcycles that have a hollow fork stem.

This is ideal for a compact installation of Garmin zumo or TomTom Rider motorcycle GPS devices on your bike. The 4-hole AMPS pattern also matches the genuine Garmin Montana and inReach AMPS cradles as well as a huge range of other manufacturers’ devices.

The 4-hole AMPS pattern dimensions are approximately 31mm x 38mm (1.188” x 1.496”). The holes are arranged in a rectangular pattern and has been adopted as an industry standard for mounting electronic devices.

The socket slots securely over 25mm (1 inch) balls and is compatible with 25mm ball mount systems from RAM Mount, SW-Motech and many more.

Simple to fit, this fork stem mount has an almost custom look. Unlike other fork stem products, the Ultimateaddons motorcycle fork stem mount uses aluminium sleeves for a secure and durable fit. It features a machined upper ring to finish off the installation and a stainless-steel bolt for ultimate corrosion protection.

Simple to fit, just slide the attachment into the hole of the stem and tighten the bolt which will move the two clamping sleeves apart to create a tight fit. The fork stem kit is designed to fit into the steering head tube of fork stems and will work with various stem sizes.

This aluminium fork stem attachment is supplied with a 25mm (1") ball connector which is compatible with 1” B Size RAM Mount components.

Please note - This mount is not suitable for every motorcycle measure the internal diameter of your motorcycle’s fork stem prior to purchasing. (There may be a cap covering the fork stem on certain motorcycles)
