The EK CHAIN 520SRX2 13/49 chain kit is aimed at motocross riders looking for a robust and lightweight set for their transmission. Coming from the SRX series, this reference strikes a good balance between quality and price, with regular updates to maintain performance in demanding terrain.
- Type: 520 chain kit (sprocket 13 / crown 49)
- Chain: 114 links, steel/steel color
- Crown: ultra-light aluminum, designed to reduce mass
- Pitch: 520
- Weight: 1.54 kg (for 100 links)

The lightweight aluminum crown limits unsprung mass and rotational weight, while the SRX2 chain offers a construction suited for off-road demands. This kit is particularly relevant for enduro/motocross — to be installed during a service or when changing gearing to adjust response and usage range.
