The D.I.D 520ERT3 120L Gold racing chain is designed for high-performance off-road motorcycles and other compatible 520 chain applications. Manufactured by D.I.D, this chain uses the manufacturer part number 520ERT3120RB and vendor part number 520ERT3120RB for reliable identification and fitment reference.
Built for motocross, enduro, and competition riding, the 520ERT3 series combines a lightweight design with strong tensile performance and efficient power transfer. The gold finish provides a distinctive appearance while the chain’s race-focused construction is intended to support demanding riding conditions. The 120-link length is suitable for motorcycles requiring a standard 520-size replacement chain, subject to the original equipment configuration and final gearing setup.
Fitment should be verified against the motorcycle manufacturer’s specifications, including chain size, required link count, sprocket compatibility, and any gearing changes. This D.I.D chain is supplied as a 520-size, 120-link assembly and may require adjustment or professional installation to achieve the correct slack and alignment.
