⛓️ DID 420 & 520 Drive Chains – Precision Performance You Can Trust

Trusted worldwide by professional riders and OEM manufacturers, DID chains are known for their strength, durability, and smooth performance. Whether you're upgrading your electric dirt bike, motocross machine, or street build, the DID 420 and 520 chains deliver high-efficiency power transfer and long-lasting reliability for riders who demand the best.

🔧 What’s the Difference?

• DID 420 Chain
  Ideal for lightweight bikes such as the Sur-Ron Light Bee, Segway X160/X260, and youth pit bikes. Lighter and narrower than 520 chains, it's optimized for bikes under 15–20 HP.

• DID 520 Chain
  Built for higher-powered bikes like the Sur-Ron Ultra Bee, motocross bikes (125cc+), and mid-size street or supermoto builds. Offers increased strength and wear resistance.

✅ Features & Benefits

• 🏆 Proven DID Quality
  Manufactured in Japan using advanced heat treatment and precision engineering for top-tier strength, smooth operation, and minimal stretch.

• 💪 High Tensile Strength

  • 420 Chain: ~4,200–4,500 lbs tensile strength

  • 520 Chain: ~7,850+ lbs tensile strength (varies by model: standard vs. X-ring)

• ⚙️ Extended Lifespan
  Available in standard, heavy-duty, or sealed (X-ring) variants for increased wear resistance and reduced maintenance.

• 🔩 Compatible Sizing Options
  Available in multiple link lengths (e.g., 100L, 120L) and easily adjustable to fit custom sprocket setups.

• 🛡️ Corrosion Resistant
  Some models feature gold or black plating for additional rust resistance and a premium look.

• 🧰 Easy to Install
  Can be installed with or without a master link clip (select models); rivet-type available for performance builds.
