At DMG Motorsports, we present the D.I.D 520ERT3 Rivet Master Link (ZJ520ERT3G) — the genuine replacement connecting link engineered specifically for D.I.D's legendary 520ERT3 motocross chain. D.I.D's 520ERT3 is the #1 selling motocross chain and is used by factory race teams such as Monster Energy Kawasaki, Star Racing Yamaha, Honda HRC, Troy Lee Designs/Red Bull GasGas, Red Bull KTM, Factory HEP Suzuki and more! This rivet-style master link lets you complete or repair your 520ERT3 chain with a connection every bit as strong as the rest of the chain, and it's finished in matching gold to preserve that factory look. Whether you're building up a fresh chain or servicing one already on your bike, DMG Motorsports has you covered with a link that's purpose-built for this exact chain series.

Features:

• Genuine D.I.D rivet-type (ZJ) connecting link designed exclusively for the 520ERT3 chain series
• Gold-plated finish to match the 520ERT3 chain's factory-style gold inner and outer links
• Rivet-style construction delivers a permanent, high-strength connection — installation requires a chain press/rivet tool
• Fits ONLY the 520ERT3 chain and is not compatible with the older 520ERT2 chain, so master links are not interchangeable between chain models
• Backed by D.I.D's reputation for strength-to-weight performance trusted across motocross racing disciplines, especially in the 250 class
• Ideal for riders building a new 520ERT3 chain or replacing a worn master link during routine chain maintenance
