Features

EK CHAIN 520RRX NX-Ring 520 - Manufacturer reference: 520RRX-G/G 116 MLJ

EK 520RRX NX-Ring transmission chain in gold/gold finish, designed for demanding road and off-road use. Part of the EK racing range used in numerous competitions (JSB1000, Suzuka 8 Hours, ST600, J-GP2, J-GP3, JP250), this chain is aimed at riders looking for a robust and reliable part for transmission.

Type: 520 NX-Ring chain
Number of links: 116
Color: Gold / Gold
Pitch: 520
Durability index (100 links): 3500
Weight (kg / 100 links): 1.56 kg

The NX-Ring design offers a sealing system for the links suitable for the stresses of road and off-road, limiting dirt intrusion and allowing for long-lasting lubrication. Ideal for Quad, Urban, Cross, and Roadster applications, it fits a wide range of primary transmissions and can suit popular models such as KTM 690 SMC R (2026), HONDA CRF 300 L (2026), or DUCATI 950 HYPERMOTARD SP (2025), after verifying the number of links and the sprocket/crown adjustment.

Choose this EK chain for a transmission that combines racing aesthetics and meticulous finishing — a key element for maintaining torque and precision between sprocket and crown.
