EK 520M3 520 Transmission Chain (manufacturer part number: 520M3-G/G 120 SPJ) — a motocross chain with a gold treatment, designed for the demands of sprocket/crown connections on off-road and road machines. Engineered to minimize friction while providing strong resistance to tension and abrasion, it combines durability and a polished appearance for riders who care about reliability and style.
Suitable for Quad, Cross, and Roadster environments, this chain is aimed at riders looking for a robust transmission for their motorcycle or quad. It is particularly well-suited for installations on small to medium displacement models as well as demanding cross models. Examples of common compatibilities include: KTM 125 SX (2025), HONDA CRF 450 R (2024), and HUSQVARNA SVARTPILEN 125 (2024).
Install it with a sprocket and crown in good condition, lubricate and tension according to the manufacturer's recommendations to optimize the chain's longevity. The gold treatment provides abrasion protection while giving a polished aesthetic to the transmission.
