CNC 84 mm Rear Caliper Bracket - BMW R1300

CNC 84 mm rear caliper bracket for BMW R1300

Plug & play fitment, increased rigidity and refined finish

Optimize your BMW’s rear braking with this CNC-machined rear caliper bracket, designed to accept 84 mm bolt-spacing calipers (for example, GP2-SS). Developed specifically for the BMW R1300 platform, it mounts directly to the stock fixing points with no cutting or adaptation. The result: a clean, reliable installation with perfect alignment.

Made from a high-strength aluminum alloy, this bracket offers superior rigidity that limits deformation during hard braking and improves bite consistency. Its precise geometry ensures ideal positioning of the caliper and disc for a firmer pedal feel and even pad wear. To simplify installation and ensure correct tightening, the torque value is indicated directly on the part.

Whether you’re after better control under heavy use, a more technical look, or compatibility with a performance 84 mm caliper, this bracket provides a reliable, durable base to upgrade your R1300’s rear braking.

Why upgrade the stock part?

The stock setup is designed for versatile use, but it limits upgrades to high-performance 84 mm calipers. Depending on intensity of use, a less rigid bracket can lead to a less defined brake feel, vibrations, or uneven pad wear.

• Not possible to easily install a high-performance 84 mm caliper

• Stock bracket rigidity sometimes insufficient for sustained use

• Setups requiring non-optimal adaptations or spacers

This dedicated solution installs without modification on BMW R1300s, ensures high rigidity, and opens the door to 84 mm calipers (e.g., GP2-SS) for rear braking that’s more precise, durable, and confidence-inspiring.

Ideal use:

• BMW R1300 owners seeking a clear improvement in rear braking

• Fitting a performance 84 mm caliper (e.g., GP2-SS)

• Dynamic road riding, long-distance travel, and loaded bikes

• Builders and enthusiasts aiming for a technical look and clean install

• Demanding riders wanting a more precise, consistent pedal feel
