EK 428SR 428 Transmission Chain — Manufacturer Ref: 428SR-STL 120 SPJ
The EK 428SR is a robust transmission chain designed for small trails, roadsters, and off-road motorcycles. Part of the SR series, it maintains great flexibility even after long hours of use thanks to a design aimed at reducing link stiffening. The plates benefit from a specialized heat treatment to enhance durability and wear resistance without claiming unverified performance.
Designed to pair with common sprockets and crowns, this chain will suit riders looking for a reliable wear part for maintenance or restoration. Examples of compatibility include: YAMAHA YZ 85 LW BIG WHEELS 19/16 (2026), HONDA CB 125 R (2025), BENELLI TORNADO NAKED T 125 (2025). Be sure to check the number of links and fit before installation and adhere to regular lubrication and wear checks to maximize longevity.
