The EK/JT 428ZVX 14/49 chain kit is designed for discerning riders seeking a reliable transmission system for their roadster. Composed of a 428 ZVX series chain and a standard steel sprocket, this kit provides a complete solution for replacing the sprocket and rear crown while maintaining a sleek steel appearance. The ZVX series from EK CHAIN is engineered for good rigidity and durability suited for sustained road use.
Designed for roadsters and small displacement bikes requiring a robust transmission, this kit is particularly suitable for Yamaha SR 125 models (1996‑1998) depending on the sprocket/gear set. Regular installation and maintenance (tension, lubrication) will ensure even wear. Manufacturer reference: Not provided.
