Chain-through protection for Yamaha YZF-R1/M RN32, RN49 & RN65 2015–2026. CNC protective part for more safety in the drive area of your R1. This chain-through protection from Hesterberg-Cad/Cam was developed for the Yamaha YZF-R1 and YZF-R1M in the RN32, RN49 and RN65 model lines. It fits models from 2015 to 2026 and replaces the original plastic part with a precisely machined aluminum solution.

Especially on high-performance motorcycles like the Yamaha R1, enormous forces act in the area of the chain, sprocket and engine casing. If a chain break occurs, a stable chain-through protection made from aluminum 7075-T6 can help effectively protect the engine casing from serious damage.

Robust upgrade instead of the standard plastic part

The original plastic part fulfills its basic function in everyday use, but it doesn’t offer the same material feel and rigidity as a CNC-machined aluminum component. This Yamaha R1 chain guard addresses exactly that: high-quality material, precise manufacturing, and a clearly defined technical function.

Whether for trackdays, race track use, or a sporty performance build — the Hesterberg-Cad/Cam chain-through protection is a worthwhile detail for riders who want to upgrade their R1 not only visually, but also functionally.

Designed for riders who seriously put their R1 to work

With a Yamaha YZF-R1 or R1M, every technical detail matters. Many riders invest in Suspension, brake system, tires, Wheels / Rims or fairing — but protective parts in the drive area are also important when the motorcycle is used regularly in a sporty way.

A chain failure can cause significant secondary damage. This CNC chain-through protection for the Yamaha R1 helps to better secure the sensitive area on the engine casing and replace the original plastic component with a higher-quality solution.

Important compatibility note

The chain-through protection replaces the original plastic component. After installation, the chain guard cover is no longer compatible.

Please check before installation whether your motorcycle has any additional fitment parts in the area of the chain, sprocket, or chain guard.
