DID 520VX3-106 Steel 106 Link High Performance X-Ring Chain - Strong

Our review of the DID 520VX3-106 finds it best suited for riders who need a durable, high-performance roller chain for street, ATV, or off-road bikes up to 800cc. The single biggest reason to consider this chain is its upgraded rigidity and seal design, which translate into better throttle response and longer seal life compared with earlier generations. Installers who value a robust clip-style master link and a relatively light weight for its strength will appreciate the practical balance DID aimed for with this VX3 series chain.

Key Features

• Upgraded VX3 design: Provides improved rigidity for more direct energy transfer and crisper throttle response on acceleration.
• X-ring seals: Enhanced X-ring retention boosts seal durability and reduces lubricant loss over extended use.
• Wide application range: Sized and rated to fit many street, ATV, and off-road machines up to 800cc, covering a broad set of riders.
• High tensile strength: Average tensile strength around 8,210 pounds delivers confidence under load for aggressive riding.
• Included master link: Ships with a clip-style connecting link for straightforward installation without special tools.

Who It's For

This chain is aimed at riders of mid- to large-displacement motorcycles and ATVs who need a reliable, upgrade-level drive chain that improves throttle feel and holds up to varied terrain. Mechanics and DIY installers will like the common clip-style master link and familiar 520 sizing that fits many common sprockets.

Those who should look elsewhere include riders with machines above 800cc or machines that require a different pitch or specialty chain type, since the 520 VX3 is optimized for applications up to roughly 800cc and standard 520 chain fitments.

Pros & Cons

Pros

• Notable improvement in throttle response thanks to the Direct Energy Transfer design.
• Durable X-ring seals with better retention extend sealing life and reduce maintenance intervals.
• Good balance of strength and weight, with an average tensile rating of 8,210 lb and reasonable weight for its class.
• Wide compatibility with street, ATV, and off-road applications up to 800cc.

Cons

• Some buyers report inconsistency about whether a master link is included, so double-check contents before installation.
