D.I.D. - 520 MX Gold Racing Chain

The D.I.D. 520 MX Gold and Black Chain is one of our most popular for a reason — it’s built to take serious abuse and keep coming back for more. With an impressive 8,930 lbs. tensile strength, this non-sealed chain shrugs off the pounding of deep ruts, hard launches, and long motos without stretching or slowing you down. It’s the same chain trusted by Troy Lee Designs/Red Bull GasGas, Red Bull KTM, and 8X ATVMX champ Chad Wienen, so you know it’s the real deal.

Why we like it: it’s all about strength, simplicity, and that crisp D.I.D. feel. The gold-and-black finish looks factory clean, while the lightweight, high-tensile design keeps your power delivery snappy and efficient. It comes with a clip-style master link for easy setup and fits perfectly for 450-class bikes or anyone chasing race-level reliability.

Why it’ll work for you: the 520MX’s high-tensile steel construction means less stretch and more consistent power transfer over time. The solid, non-sealed design reduces drag for maximum horsepower, while the gold-and-black plates offer both corrosion resistance and a clean, pro-level look. Engineered to handle up to 500cc machines, it’s the perfect mix of durability, performance, and weight — ready to run hard in any off-road condition.
