Hesterberg-Cad/Cam Rear Brake Caliper Bracket 64mm Quick-Change System – Yamaha YZF-R6 RJ27 (2017–2026)

Shaving over 500 g of unsprung rear-wheel mass while making tyre changes genuinely faster in the pits — the Hesterberg-Cad/Cam 64 mm rear brake caliper bracket is the practical, no-compromise upgrade that busy trackday and club-racing R6 riders actually reach for. Designed specifically for the Yamaha YZF-R6 RJ27 (2017–2026), this CNC-machined aluminium anchor bracket pairs with a compatible 64 mm aftermarket brake caliper to turn what was once a fiddly rear-wheel swap into a clean, repeatable process.

Key Features

• Drops over 500 g compared to the OEM rear brake setup — meaningful unsprung mass savings on a chassis built for precision handling
• 64 mm caliper mount accepts compatible 64 mm aftermarket brake calipers for a secure, rattle-free fit
• Precision CNC-machined from high-grade aluminium 7075-T6 for a tight fit and long service life under race conditions
• Quick-change design: threaded holes in the chain tensioner allow the bracket to stay attached during rear-wheel removal, keeping the caliper in position and preventing pads from falling out
• Available in natural or black anodised finish — both versions weigh approximately 0.160 kg
• Supplied complete with all required mounting bolts

Everyday Usability at the Track

The real-world argument for this bracket is simple: faster, less stressful rear-wheel changes. On a standard R6, removing the rear wheel can mean wrestling a loose caliper, watching brake pads slide out of position, and losing precious time in the pit lane. The Hesterberg-Cad/Cam quick-change system solves that by threading the bracket directly to the chain tensioner. When you slide the axle out, the caliper rides with the bracket — staying put, staying clean, staying ready for the wheel to go straight back in.

For riders who compete at club level, run regular trackdays, or simply want a more organised, professional pit setup, that repeatability has an everyday value that goes beyond the weight saving alone. Less improvisation, fewer dropped pads, and a rear-wheel change that looks as tidy as it feels.

Build Quality and Materials

Hesterberg-Cad/Cam manufactures this bracket from aluminium 7075-T6, the same alloy specification used in aerospace and high-load racing applications. CNC machining ensures dimensional accuracy throughout, so the 84 mm mounting interface registers cleanly every time. The anodised surface treatment — whether you choose the understated natural finish or the sharper black — adds corrosion resistance and protects against the heat cycles typical of track use.

Weight and Handling

Unsprung mass at the rear wheel has a direct influence on how quickly the suspension can follow the road surface and how precisely the chassis responds to throttle and braking inputs. At over 500 g lighter than the OEM rear brake setup, this bracket makes a measurable contribution to the R6's already sharp responses. For a motorcycle that rewards precision, removing unnecessary weight from the rear axle area is one of the more effective modifications available at this price point.

Fitment and Compatibility

This bracket is designed exclusively for the Yamaha YZF-R6 RJ27, covering all model years from 2017 to 2026. It requires a compatible 64 mm aftermarket brake caliper — it is not designed for use with the original OEM caliper. A new brake line is also required as part of the installation. Fitment by a qualified mechanic is recommended.

Important Usage Notes

• No type-approval certificate — for track use only
• Not approved for use on public roads
• A new brake line is required upon installation
• Compatible with 64 mm aftermarket brake calipers only — not for use with the OEM caliper
• Installation by a qualified and experienced mechanic is strongly recommended
