EK/PBR 520SRX2 Chain Kit 14/43 - Hardened Ergal Sprocket
The SRX series from EK CHAIN offers a balanced compromise between performance and value, recognized by many roadster riders. This 520SRX2 chain kit comes in a gold finish (chain and link), with a 14-tooth sprocket and a 43-tooth hardened Ergal sprocket, designed to combine lightness and strength.
Designed for road use, this kit is suitable for common transmission adjustments and will facilitate standard maintenance interventions (tensioning, lubrication, and replacement). The Ergal sprocket provides a significant weight reduction without compromising the mechanical performance expected on the road.
Among the models for which this setup is often chosen: Yamaha MT-03 (2025 - 320 cc), Yamaha R3 (2025 - 300 cc), and Yamaha MT-03 ABS (2022 - 320 cc). Brand: EK CHAIN. Manufacturer reference: not provided.
