EK 428SR 428 Transmission Chain — Manufacturer Ref: 428SR-STL 116 SPJ
Designed for urban, off-road, and roadster use, the EK 428SR chain is a robust and versatile transmission. The SR series focuses on an architecture that maintains the chain's flexibility even after long hours of riding. The plates have undergone a specific heat treatment to enhance their durability and wear resistance, without compromising the flexibility of the links — a key advantage for ensuring precise engagement on the sprocket and crown.
Suitable for lightweight motorcycles and off-road machines, this 428SR is particularly compatible with YAMAHA YZ 85 LW BIG WHEELS 19/16 (2026), HONDA CB 125 R (2025), and BENELLI TORNADO NAKED T 125 (2025) models. Whether you're reassembling a transmission after an enduro outing, restoring a roadster, or maintaining an urban quad, the EK 428SR provides a reliable solution to effectively transfer power to the rear wheel.
