EK/PBR 428SR Chain Kit 14/52 - Standard Sprocket
Complete chain kit by EK CHAIN, designed for roadsters seeking a reliable and easy-to-maintain transmission. The SR series uses a specific heat treatment on the plates to preserve the flexibility of the chain even after long use, while increasing wear resistance.
Suitable for roadster motorcycles like the YAMAHA MT-125 (2023–2025 models), this kit comes ready to install for those skilled in fitting a sprocket and a chain. To optimize longevity, regularly check the tension, lubricate, and remove dirt. This kit emphasizes robustness and durability without unverified technical promises: it provides a reliable replacement solution for your transmission.
