If you run your Yamaha YZF-R9 RNA3 on track days, rear wheel changes eat into your session time more than almost anything else. The Hesterberg-Cad/Cam 84mm rear brake caliper bracket solves the problem directly: its quick-change design keeps the HEL 2-piston brake caliper under control during wheel removal, turning a fiddly job into a clean, repeatable process that costs you far less time in the paddock.
Key Features
- Engineered specifically for the Yamaha YZF-R9 RNA3 model years 2025 and 2026
- 84mm mounting pitch matched to the HEL 2-piston brake caliper — no improvisation required
- CNC-machined from 7075-T6 aluminium for a lightweight, precision fit at approximately 0.291 kg
- Quick-change system holds the caliper in position during rear wheel removal, preventing it from dropping and keeping brake pads seated
- Threaded holes allow direct connection to the chain tensioner, so the bracket stays located when the wheel is out
- Available in natural or anodised black finish to suit your build aesthetic
- Supplied with all required mounting bolts — ready to fit straight from the box
Designed Around Paddock Reality
Anyone who has wrestled a rear wheel off a track bike mid-session knows how quickly an awkward brake caliper can derail a tyre change. The Hesterberg-Cad/Cam bracket addresses this not with complexity, but with considered engineering. By incorporating threaded holes into the chain tensioner interface, the bracket anchors the caliper in a fixed, predictable position the moment the axle comes out. There is no scrambling to catch a falling caliper, no risk of displaced brake pads, and no time wasted resetting everything before the wheel goes back in.
The result is a measurably more efficient rear wheel change — fewer moving variables, less stress on the crew, and a more professional workflow whether you are running a one-man trackday setup or a full pit crew.
Construction and Finish
The bracket is CNC-machined from 7075-T6 aluminium, the same alloy grade found in high-load aerospace and motorsport components. At approximately 0.291 kg it adds virtually nothing to unsprung weight while delivering the rigidity a brake anchor demands. Both the natural and anodised black finishes are production-standard — this is a functional racing component built to work, not a cosmetic add-on.
Fitment and Compatibility
This rear brake caliper bracket is designed exclusively for the following fitment:
- Yamaha YZF-R9 RNA3 — model years 2025 and 2026
- Compatible only with the HEL 2-piston brake caliper — do not attempt to fit other calipers without independent technical verification
- Position: rear wheel / rear axle
- 84mm caliper mounting pitch
A new brake line is required for installation. Fitting work on brake systems and wheel alignment is safety-critical and should be carried out by qualified personnel.
Important Notes
- No type approval or road-use certification — track use only
- Not approved for use on public roads
- A new brake line must be fitted during installation
- Compatible exclusively with the HEL 2-piston brake caliper
- Professional installation is strongly recommended
