EK 520MVXZ2 QX-Ring Chain 520 — Manufacturer reference: 520MVXZ2-STL 114 MLJ
Designed by EK CHAIN for demanding machines, this 520MVXZ2 QX joint chain offers a robust construction suitable for urban, road, and off-road use. The side plates feature relief holes to reduce unsprung mass, while the large diameter pins increase rigidity and wear resistance. The QX joints limit friction losses and contribute to more stable internal lubrication.
This chain is aimed at riders looking for a durable and high-performance transmission part for roadsters, sport bikes, trails, enduros, or vintage models. It fits 520 setups and is compatible with a wide range of displacements — examples of compatibility include KTM 690 SMC R, HONDA CRF 300 L, DUCATI 950 HYPERMOTARD SP. Installation, adjustment, and regular maintenance are essential to get the best out of the chain and preserve the sprocket and crown.
