DID 520 NZ is a high-performance non-sealed 520 drive chain, ideal for vintage and lower-displacement off-road bikes. Built to outperform typical OEM non-sealed chains with added strength and longer service life.
DID 520 NZ Chain is a durable, high-performing non-sealed drive chain designed for riders who want strong power transfer and better longevity than a typical OEM non-sealed chain. It’s a great choice for vintage and lower-displacement off-road bikes where low drag and crisp drivetrain response matter.
Thanks to DHA pin treatment (a hard chromium-carbide layer on the pin surface), plus quad-stake riveted pins and solid bushings, this chain delivers excellent strength and wear resistance for demanding track and trail use—without the added friction of sealed designs.
Built by DID, a trusted name in drivetrain components, this chain is made for riders who want proven strength and smooth performance in a non-sealed format. It’s a smart, cost-effective upgrade for keeping your bike’s final drive reliable and responsive.
