Product details :

Features

EK 520SRX2 QX-Ring Drive Chain — by EK CHAIN, manufacturer reference: 520SRX2-G/G 126 MLJ. Part of the SRX series, this chain offers a good balance between performance and price, designed for riders seeking reliability and longevity on roads, trails, and tracks.

Type: QX-Ring (sealing rings between links)
Pitch: 520
Number of links: 126
Color: Gold / Gold
Weight: 1.54 kg (for 100 links)
Relative lifespan index: 3300 (for 100 links)

The QX-Ring seals reduce oil loss between rollers and pins, contributing to controlled wear when the chain is properly tensioned and lubricated. Suitable for demanding transmissions, it is ideal for Quad, Urban, Motocross, and Roadster uses. Perfect for installations on trail or supermoto machines where robustness and transmission consistency are sought.

Specifically suitable for recent models such as GAS GAS SM 700 (2026), KTM 690 SMC R (2026), and YAMAHA YZ 450 F (2026) — always check compatibility of length and tension adjustment before installation. Regular maintenance and tension checks will prolong the life of the chain.
