The standard steel PBR sprocket - 520 (manufacturer reference 504 46 C45) is a final drive component designed for road use and high revs. Made from an 18NCD5 steel alloy developed from competitive experience, it offers precise tooth profiles and a discreet black finish suitable for demanding roadsters.
This sprocket is designed for longevity and resistance to corrosion and abrasion, while providing an optimised tooth profile to minimise friction between the chain and the sprocket. Ideal for riders seeking a robust component for sporty road use, it easily integrates into the final drive after installation in accordance with manufacturer recommendations.
Compatible with many modern roadsters — for example, KAWASAKI NINJA 500 SE (2026), YAMAHA R9 (2025), and SUZUKI GSX-R 1000 R ABS (2021) — please check compatibility with your model before installation. Professional installation is recommended if you are not equipped for transmission maintenance.
