Features

EK/PBR 520SRX2 Chain Kit 13/51 - Standard Sprocket

Designed for off-road use, this EK CHAIN SRX2 chain kit includes a chain, a 13-tooth sprocket, and a 51-tooth standard sprocket configuration. The SRX series offers a good balance between performance and cost, suitable for motocross riders who are replacing their transmission to regain predictable handling and controlled wear.

Type: 520 Chain Kit (SRX2)
Links: 114
Pitch: 520
Color: Gold/Gold
Sprocket: Steel (standard)
Weight: 1.54 kg / 100 links
Durability Index (reference): 3300 (based on 100 links)

The gold finish facilitates visual wear detection and provides a neat aesthetic on enduro/cross machines. Classic installation: tension control, lubrication, and alignment adjustment are recommended during installation and regular maintenance to preserve the longevity of the kit.

Compatible with many off-road machines — including YAMAHA WR 250 F (2026), FANTIC XEF 310 (2025), and FANTIC XEF 250 (2025) — this kit is aimed at riders looking for a robust and easy-to-install replacement part.
