Hesterberg-Cad/Cam Rear Brake Caliper Bracket 64mm Quick-Change System – BMW S1000RR K67 (2019–2021)

Machined from aerospace-grade aluminium 7075-T6 and finished to exacting tolerances, this Hesterberg-Cad/Cam rear brake caliper bracket is the kind of component that rewards the detail-obsessed track rider. Designed exclusively for the BMW S1000RR K67 (2019–2021), it pairs a 64mm caliper mount with an intelligent quick-change system that transforms rear wheel swaps from a fumbling ordeal into a clean, controlled operation — saving over 500 g of unsprung mass compared to the OEM setup in the process.

Key Features

• CNC-machined from high-strength aluminium 7075-T6 for an outstanding strength-to-weight ratio
• 64mm caliper mount accepts a compatible aftermarket brake caliper for a secure, repeatable fit
• Quick-change system allows the rear wheel to be removed without the caliper or brake pads falling free
• Threaded interface allows direct connection to the chain tensioner, keeping the caliper stable throughout the wheel removal process
• Over 500 g of unsprung mass reduction possible versus the standard OEM setup — a meaningful gain for handling and suspension response
• Available in natural aluminium or black anodised finish; all necessary mounting hardware included

CNC Precision and Material Excellence

Where OEM brackets prioritise road compliance and broad tolerances, the Hesterberg-Cad/Cam unit is engineered around the demands of the pit lane. The bracket is CNC-machined from aluminium 7075-T6 — the same alloy found in aerospace and high-end motorsport components — delivering exceptional rigidity with a finished weight of approximately 0.210 kg. Every surface, bore and thread reflects the precision of computer-aided manufacture rather than a compromise between cost and performance.

Two finish options are offered: natural aluminium, which keeps the machined aesthetic clean and functional, or a black anodised treatment that adds a layer of corrosion resistance alongside the visual contrast that suits a stripped-back track build.

Faster Rear Wheel Changes in the Paddock

The engineering logic behind this quick-change system goes beyond simply repositioning the caliper. With a conventional OEM setup, removing the rear wheel risks dislodging a brake pad — an event that can turn a 30-second tyre swap into several minutes of unplanned work. The Hesterberg-Cad/Cam bracket eliminates that risk entirely.

By connecting directly to the chain tensioner via threaded bores, the bracket holds the aftermarket caliper securely in position as the wheel slides out. The result is a repeatable, controlled process that suits the rhythm of a busy trackday or a competitive race weekend, where every minute in the paddock counts.

Note that installation requires a new brake line and should be carried out by qualified personnel familiar with motorcycle braking systems.

Fitment and Compatibility

This rear brake caliper bracket is developed specifically for the BMW S1000RR K67, covering model years 2019, 2020 and 2021. It is intended for use with a compatible aftermarket brake caliper only — it is not suitable for the original OEM caliper. Always verify caliper compatibility before ordering.

Important Notes

• No type approval or road-use certification — track use only
• Not approved for use on public roads
• A new brake line is required upon installation
• Compatible with a suitable aftermarket brake caliper only; not for use with the original OEM caliper
