Hesterberg-Cad/Cam Rear Brake Caliper Bracket 84mm Quick-Change System – Aprilia RSV4 / RR / 1100 Factory (2021–2026)

Pit-stop efficiency starts with the right hardware. The Hesterberg-Cad/Cam 84mm rear brake caliper bracket relocates the caliper to its lower, traditional position, turning a fiddly rear-wheel removal on the 2021–2026 Aprilia RSV4, RSV4 RR and RSV4 1100 Factory into a clean, controlled procedure that saves real time in the paddock. Engineered exclusively for track use, it is the kind of precision component that separates a well-sorted race bike from one that costs you laps in the pits.

Key Features

• Quick-change system that relocates the rear brake caliper from the factory upper position to the proven lower position, dramatically simplifying rear-wheel removal
• Compatible with the original Aprilia rear brake caliper — no replacement caliper required
• Threaded connection points allow the brake anchor to be bolted directly to the chain tensioner, keeping the caliper securely in place during wheel changes and preventing it from dropping free
• Mounting hardware included — all necessary bolts are supplied in the box
• Available in natural or black anodised finish to suit your build aesthetic
• Lightweight precision construction at approximately 0.271 kg — every gram counts at the track

Why the RSV4's Factory Caliper Position Creates a Problem

From the 2021 model year onward, Aprilia repositioned the rear brake caliper above the brake disc on the RSV4 to accommodate the undercut swingarm design. While functionally sound on the road, this arrangement makes rear-wheel removal considerably more involved in a race or trackday environment where quick tyre changes are essential. Every extra step costs time and creates the risk of the caliper swinging free and damaging brake lines or the disc itself.

The Hesterberg-Cad/Cam bracket restores the lower caliper position that race technicians and experienced trackday riders know and trust. Installation is largely plug-and-play with the original caliper, and the bracket interfaces with the chain tensioner via dedicated threaded bores to give you full control throughout the wheel-change process. The one additional requirement is a new rear brake line of appropriate length — factor this into your build from the outset.

Build Quality and Construction

Designed and produced by Hesterberg-Cad/Cam — a specialist known for precision-machined race accessories — this bracket is offered in two finishes. Natural aluminium carries a clean, functional look that suits unpainted or raw-finish builds, while the black anodised option provides a harder surface layer and a stealthy aesthetic. Both variants deliver the same dimensional accuracy and fitment quality that track use demands.

For best results, it is recommended to swap the left and right chain tensioners during installation. Fitting should be carried out by qualified personnel with experience in race brake systems.

Fitment and Compatibility

This rear brake caliper bracket is designed specifically for the following Aprilia models:

• Aprilia RSV4 (2021–2026)
• Aprilia RSV4 RR (2021–2026)
