DescriptionThe whole story▼
Every component on a BMW M1000RR should match the precision of the machine itself. This CNC-machined chain guard from Hesterberg-Cad/Cam replaces the original plastic and sheet steel part on the M1000RR K66 (2021–2026) with a precisely engineered aluminium solution that earns its place on road and track alike.
Key Features
- Direct replacement for the original plastic and sheet steel chain guard on BMW M1000RR K66 models from 2021 to 2026
- CNC-machined from aerospace-grade aluminium 7075-T6 for exceptional rigidity and corrosion resistance
- Lightweight at approximately 0.248 kg — a genuine upgrade without unnecessary mass in the drivetrain area
- Available in natural aluminium or black anodised finish to suit your build aesthetic
- Motorsport-oriented construction that integrates cleanly into trackday, racing and performance setups
- Precision-manufactured by Hesterberg-Cad/Cam to exacting tolerances
A Drivetrain Upgrade Worthy of the M1000RR
The BMW M1000RR K66 is built around uncompromising performance, and the components surrounding the swingarm and rear wheel should reflect that. The stock chain guard does its job, but it is a production compromise — moulded plastic backed by sheet steel. The Hesterberg-Cad/Cam unit swaps that out for a single CNC-machined piece of aluminium 7075-T6, a high-strength alloy more commonly found in aerospace and motorsport applications than in mass-produced parts.
The result is a component that not only looks the part in any stripped-back or race-prepared M1000RR, but also offers superior durability in the demanding environment around the chain, swingarm and rear wheel. Whether you are building a dedicated track weapon or simply raising the standard of every component on your superbike, this chain guard represents a considered, purposeful choice.
