DID 520 VX3 Gold 120-Link X‑Ring Motorcycle Chain — High Strength, Improved X‑Ring Retention

The DID 520VX3GB-120 is a 120-link, gold-finished VX3 X-ring chain engineered for high-performance street, ATV and off-road bikes up to 800cc, featuring improved rigidity, enhanced X-ring retention and a clip-style master link for easy installation.

This DID VX3 chain is the next step after the popular 520 VX2, redesigned to deliver sharper throttle response and longer seal life through DID's Direct Energy Transfer improvements and upgraded X-ring technology. Built to withstand demanding riding conditions, the chain balances tensile strength, light weight and durability for riders who expect dependable power transfer without excess mass.

How does the VX3 chain improve throttle response?

The DID VX3 uses Direct Energy Transfer engineering to reduce flex and improve lateral rigidity, meaning more of your throttle input reaches the rear wheel with less loss. The result is a crisper feel under acceleration and a more connected riding experience.

• Direct Energy Transfer design increases stiffness for quicker power delivery
• Optimized plate geometry reduces energy loss between sprockets
• X-ring seals retain lubricant and reduce internal friction for smoother operation

Is this chain suitable for my bike or ATV?

The 520VX3GB-120 fits machines that require a 520 pitch chain and supports a wide range of applications up to 800cc, including many street bikes, dual-sport, and utility ATVs. Confirm chain pitch, width and link count against your vehicle's requirements before ordering.

• 520 pitch — standard size for many midweight motorcycles and ATVs
• 120 links — long enough for bikes with extended swingarms or specific sprocket setups
• Compatible with street, off-road and ATV applications up to 800cc

What durability and strength features does this chain offer?

DID engineered the VX3 to raise seal retention and overall toughness compared with the VX2, delivering an average tensile strength of 8,210 pounds while keeping the chain relatively light. Enhanced X-ring retention reduces seal extrusion and wear, extending service intervals under real-world use.

• Average tensile strength: 8,210 pounds for high-load resistance
• Weight: approximately 1.52 kg per 100 links (3.35 lb) for a responsive feel
• Improved X-ring sealing system for longer life and better lubrication retention

How is the chain supplied and installed?

The 520VX3GB-120 comes as a 120-link assembly finished in gold with a clip-style master link included for straightforward installation or removal. Proper tensioning and alignment during fitment ensure optimal performance and longevity.

• Supplied as a 120-link complete chain, gold finish
• Includes clip-style master link for convenient joining or removal
• Recommended: check sprocket condition, set correct chain slack, and lubricate after installation

Who is this for? Riders and mechanics who need a high-performance replacement chain for mid-to-high-displacement machines will appreciate the DID 520VX3GB-120. It's aimed at street riders upgrading from older VX2 chains, ATV owners seeking stronger seals and riders with longer swingarms or special sprocket combinations requiring a 120-link length. Choose this chain if you want a balance of reduced weight, improved power transfer, and enhanced X-ring durability without stepping up to heavier industrial-style drive systems.
