The EK 520SRO6-114 is a Japanese-made 520-size O-ring chain designed for dirt bike, ATV, and street applications. With 114 links, this chain provides dependable fitment and long-lasting performance for compatible motorcycle and off-road drivetrain systems. Its O-ring seals retain lubricant inside the chain while helping keep water, mud, and other contaminants out, supporting smooth operation in demanding riding conditions.
Built with solid rollers and extended anti-kink bushings, the EK chain is engineered to improve durability and help extend service life. The pins are quad-staked into the side plates for secure assembly and reliable strength under repeated acceleration, impacts, and off-road use. This combination of construction features makes the EK 520SRO6-114 a practical replacement chain for riders who need consistent performance across varied terrain.
Fitment includes the 2015 Beta 390 RR; 2013, 2014, and 2015 Beta 250 RR (2T); 2011 through 2015 Beta 350 RR; and the 2015 Yamaha YZ250FX. Always compare the motorcycle manufacturer’s chain size, link count, and drivetrain specifications before installation.
