EK CHAIN 428SR - Ref. 428SR-STL 134 SPJ
The 428SR transmission chain is designed for demanding riders who seek strength and flexibility. The SR series uses heat-treated plates to enhance durability and wear resistance while maintaining the chain's flexibility over long distances. Ideal for urban use, quads, motocross, or roadsters, it adapts to transmissions where reliability and longevity are essential.
Whether you are replacing a chain on a roadster in the city, preparing a quad for adventure, or equipping a motocross machine, this 428SR offers a solid compromise between strength and flexibility. Examples of applications include: Yamaha YZ 85 LW Big Wheels 19/16 (2026), Honda CB 125 R (2025), and Benelli Tornado Naked T 125 (2025) — to be considered as potential mounting examples based on the number of links and the sprocket/crown used.
Choose an EK chain recognized for its expertise in transmission and ensure a clean, robust, and durable sprocket-crown connection on your transmission.
