The EK/PBR 520SRX2 16/43 chain kit is designed for riders looking for a simple, robust, and original replacement for their transmission. Developed in the SRX series, this kit offers a good balance between durability and price, suitable for roadsters and compact sportbikes like the listed Kawasaki Ninja ZX‑6R models.
The 520SRX2 design prioritizes reliability and compatibility: not a standard 520, steel rear sprocket for controlled wear, and mounting that conforms to original specifications. Ideal for maintenance replacement or restoration without altering the original gearing.
Compatible with several versions of the Kawasaki NINJA ZX‑6R (notably ZX600R 2015/2016 and ZX600P 2008), this kit is aimed at riders demanding a reliable wear part. Manufacturer reference: not provided.
