EK 520SROZ2 O‑Ring Chain 520 — Manufacturer reference: 520SROZ2‑STL 114 MLJ
Designed to replace the transmission on a wide range of machines, the EK 520SROZ2 chain combines modern design with proven components. Equipped with O‑rings to limit lubricant loss between the pins and the bushings, it features perforations on the plates to reduce weight without compromising strength. The links are made from heat-treated steel alloys, a result of EK CHAIN's industrial expertise.
Versatile, it is suitable for quads, roadsters, trails, sports bikes, enduros, supermotos, and vintage machines. Ideal for riders looking for a robust chain for urban, road, or off-road use, it is particularly compatible with common setups on GAS GAS SM 700, KTM 690 SMC R, or YAMAHA YZ 450 F (always check the number of links and final drive adjustment before installation).
Regular maintenance, correct tension, and appropriate lubrication will extend the lifespan of the chain. An original EK CHAIN part, designed for riders who value a reliable and easy-to-install transmission.
