EK 520ZVX3 NX-Ring 520 — Manufacturer reference: 520ZVX3-STL 122 MLJ
The EK ZVX3 chain is designed for demanding riders seeking a robust and reliable transmission. Part of EK CHAIN's premium ZVX range, this 520 is engineered to withstand the stresses of high-displacement motorcycles and versatile uses — on-road, urban, off-road, or quad. Its NX-Ring seal design limits dirt intrusion and contributes to controlled wear over the long term.
The 520ZVX3 is suitable for both a SMC 690 and a CRF 300 L or a Hypermotard 950 SP — models that are among the typical compatibilities. Ideal for replacing your original chain during a service or when changing the sprocket/crown ratio, it offers rigidity suitable for high demands while remaining easy to install and maintain.
Usage advice: check the chain slack and lubricate regularly according to your maintenance manual to maximize the lifespan of the transmission and maintain the smoothness of the drivetrain.
