DescriptionThe whole story▼
Born from track-focused engineering, the Hesterberg-Cad/Cam 64mm rear brake caliper bracket is a purpose-built quick-change solution for the Yamaha YZF-R1 and YZF-R1M across all three generations — RN32, RN49 and RN65 (2015–2026). CNC-machined from 7075-T6 aluminium and available in natural or anodised black, it carries the precise, uncompromising finish that distinguishes Hesterberg-Cad/Cam components from generic aftermarket hardware. For riders who refuse to accept unnecessary weight or wasted paddock time, this bracket redefines what a rear caliper mount can be.
Key Features
- Fits Yamaha YZF-R1 and YZF-R1M (RN32, RN49, RN65) model years 2015 to 2026
- 64mm bolt-pitch mounting accepts compatible aftermarket brake calipers directly
- Over 500 g saving compared to the standard OEM rear brake setup — every gram reclaimed at the rear wheel counts
- CNC-machined from high-grade 7075-T6 aluminium for maximum strength-to-weight performance
- Quick-change design dramatically speeds up rear wheel removal during tyre changes in the paddock
- 64mm version fits without any modification to the heat shield behind the brake disc — a decisive advantage over narrower variants
- Can be linked directly to the chain tensioner via threaded holes, keeping the caliper positively located during wheel changes
- Available in natural aluminium or anodised black finish
Design, Finish and Heritage
Hesterberg-Cad/Cam has built its reputation on components that earn their place on serious track machinery — parts developed with the same obsessive attention to material selection and surface quality that professional race teams demand. This bracket is no exception. The natural finish showcases the raw, precision-milled aluminium texture, while the anodised black option adds a deep, durable layer that resists corrosion and stands up to the thermal and mechanical stresses of repeated track use. Either way, fitment on the R1 or R1M looks entirely at home alongside other high-specification components.
The bracket weighs approximately 0.175 kg, a figure achieved through intelligent geometry rather than aggressive material removal that would compromise rigidity. This is weight saved with integrity.
Unsprung Mass Reduction — Why It Matters on the R1
At the rear wheel, unsprung mass is the enemy of feel and response. Every kilogram removed from components that move with the wheel — rather than being supported by the suspension — translates directly into sharper handling, more accurate feedback through the swingarm, and a rear end that tracks its line with greater composure under braking. The over-500 g reduction this system enables against the standard OEM setup is a tangible, measurable gain, not a marketing abstraction.
Combined with the 64mm aftermarket caliper of your choice, the Hesterberg-Cad/Cam bracket converts the rear brake assembly into a lightweight, functionally superior unit optimised for the demands of circuit riding.
Faster Rear Wheel Changes, Fewer Paddock Errors
On a track day or race weekend, a rear wheel change needs to be quick, clean and free of surprises. One of the most common frustrations with standard brake setups is the caliper pivoting or the brake pads dropping out the moment the wheel is pulled — turning a two-minute job into a ten-minute one. The Hesterberg-Cad/Cam quick-change system addresses this directly.
By introducing threaded holes into the chain tensioner, the caliper bracket can be bolted to the tensioner itself. This keeps the caliper perfectly positioned while the rear wheel is removed, eliminating the risk of it swinging loose or the pads falling out. The result is a controlled, repeatable process that saves time and reduces the scope for error between sessions.
Installation & Usage Notes
Fitting this bracket requires threaded holes to be added to the chain tensioner — a straightforward machining operation that should be carried out by a competent technician. A new brake line is required and should be specified to suit the revised caliper position. No modification to the heat shield behind the brake disc is needed with the 64mm version, which simplifies the conversion considerably compared to alternative bracket sizes.
Professional installation is strongly recommended to ensure all brake system components are correctly assembled and torqued.
Important Notes
- No road homologation or type approval — track use only
- Not approved for use on public roads
- A new brake line is required upon installation
- For use exclusively with a compatible 64mm aftermarket brake caliper
- Installation by a qualified technician is recommended
