Product details :

Features

The EK/PBR chain kit 520SRX2 13/51 is designed for motocross riders looking for a reliable, lightweight, and easy-to-maintain drivetrain. The SRX series combines a good performance/value ratio, with regular improvements integrated to stay up-to-date on challenging tracks.

Composition: steel/steel chain (plates and rollers).
Pitch: 520 — suitable for demanding off-road machines.
Number of links: 114 (delivered long, to be shortened according to installation).
Sprocket/Crown: 13/51 — traction-oriented configuration for motocross riding.
Crown: ultra-light hard anodized aluminum for better abrasion resistance.
Weight: 1.54 kg for 100 links (manufacturer reference).
Relative lifespan index: 3300 (reference for 100 links).

The hard anodized crown minimizes wear from sand and mud, while reducing the weight of the final drive — an advantage for maneuverability and direction changes on rough terrain. This kit is suitable for lightweight motocross bikes such as the Sherco 125 SE-R FACTORY (2022) and Sherco 125 SC (2019–2020). Regular maintenance and lubrication are recommended to maximize the longevity of the drivetrain.
