EK 520ZVX3 NX-Ring Transmission Chain
Manufacturer reference: 520ZVX3-G/G 110 MLJ
The ZVX series from EK CHAIN is positioned as a premium range, designed to offer rigidity and longevity across a wide variety of machines—from motocross to roadsters, urban bikes, and quads. This 520ZVX3 in gold finish is intended for high revs and intensive use where the transmission must remain reliable and controlled.
- Type: 520 Chain, NX-Ring
- Number of links: 110 (complete delivery)
- Color: Gold / Gold
- Weight: 1.8 kg for 100 links (≈ 1.98 kg for 110 links)
- Relative lifespan: 3900 (manufacturer's value for 100 links)
The NX-Ring seals present on the 520ZVX3 are designed to limit lubricant loss between links compared to a non-sealed chain, thus contributing to more controlled wear over time. Ideal for those who change their transmission after fitting a sprocket/chain kit, it adapts to standard gearing adjustments in 520.
Examples of possible installations: KTM 690 SMC R, Honda CRF 300 L, Ducati 950 Hypermotard SP. Be sure to check the pitch, the width of the sprocket, and the condition of the rear sprocket before installation, and adjust the tension according to the manufacturer's recommendations to maintain the best performance of your transmission.
