BMW K1200RS Low Profile GPS / Navigation Mount – 3 Ball Sizes

Low-profile GPS/navigation mount for the BMW K1200RS (K589).

I designed this mount because I wanted to install a navigation device centrally on my K1200RS without using a long RAM arm or a bulky handlebar mount.

The goal was simple: keep the GPS low, centered and as unobtrusive as possible, while keeping the instrument cluster and ignition key accessible.

The mounting plate is designed to sit on the center of the upper triple clamp. No drilling or permanent modification of the motorcycle is required.

I currently provide three versions with different ball/mount sizes:

• 9/16" (14.29 mm)

• 20 mm

• 1" (25.4 mm / RAM B-size)

The mount consists of a base with an integrated split clamping section and a separate threaded locking ring. Select the version matching your GPS/navigation mounting system.

Important – original BMW center cap clearance

All three mounting plates have a 45 mm diameter recess, 2.5 mm deep, on the underside. This recess is intended to provide clearance for the original BMW center cap in the upper triple clamp.

However, the 2.5 mm depth has NOT yet been physically verified with an original BMW center cap.

My own K1200RS is missing this cap, so I could not test the actual required clearance. The 45 mm diameter should provide sufficient lateral clearance, but please measure the height/protrusion of your original center cap before permanently mounting or printing the final version.

If someone with an original K1200RS center cap can provide an accurate measurement of how far the cap protrudes above the triple clamp, please leave a comment. I can update the model if necessary.

Installation

My own mount is attached to the aluminum upper triple clamp using a suitable high-strength, flexible polymer adhesive, so no holes need to be drilled in the motorcycle.

Surface preparation and adhesive selection are the responsibility of the installer. Remember that a GPS mount on a motorcycle is exposed to vibration, wind load, temperature changes and weather. Always verify that the mount is secure before riding.

Printing

My prototype was printed in PETG.

I recommend PETG, ASA or another material suitable for outdoor use and elevated temperatures. I would not recommend ordinary PLA for permanent motorcycle use because of heat and long-term outdoor exposure.

Print orientation, wall count and infill can affect the strength of the clamping section, so use appropriate settings for a functional mechanical part.

Compatibility

Designed for the BMW K1200RS (K589).

This model was designed and tested on my own early K1200RS. If you use it on another production year or configuration, please check the dimensions and available clearance before installation.

This is a hobbyist-designed part, not an official BMW or navigation manufacturer product.
