Manufacturer reference: 520SROZ2-STL 116 MLJ
Designation: EK 520SROZ2 O-Ring transmission chain 520
Designed for demanding riders who frequently change their chain kit, the EK 520SROZ2 is a cost-effective O-Ring chain. Its design incorporates thermally treated steel alloys and perforated links to lighten the overall weight without compromising strength. The O-Rings ensure the retention of the lubricating film between pins and plates, limiting oxidation and dust intrusion — an advantage on both road and off-road.
Versatile, it caters to the Quad, Roadster, Trail/Adventure, Sport, Enduro, Supermoto, Cross, Trial, Touring, Urban, and Vintage universes. Ideal for powerful models such as the GAS GAS SM 700, KTM 690 SMC R, or YAMAHA YZ 450 F, the 520SROZ2 remains a reliable choice for replacing your drive chain during a service or when switching to a chain kit.
