DID 520 VX3GB-150 Gold 150 Link High Performance X-Ring Chain

In this review of the DID 520 VX3GB-150 X-Ring chain the bottom line is simple: this chain is aimed at riders who need a durable, high-performance replacement for street, ATV, or light off-road machines up to 800cc. The reviewer found the biggest reason to buy is the combination of increased rigidity and improved X-ring retention, which together deliver crisper throttle response and longer seal life compared with earlier VX2 designs. Installation is straightforward for anyone used to working on drive trains, and the included clip-style master link (when present) keeps fitment simple.

Key Features

• Upgraded VX3 design: The VX3 improves on the VX2 with increased rigidity that helps transfer power more directly for sharper throttle feel.
• Direct Energy Transfer: DID's engineering reduces flex where it counts, producing more responsive acceleration on street and trail machines.
• Improved X-ring retention: Seals are better retained and more durable, which should slow wear and reduce the need for early replacement.
• High tensile strength: With an average tensile strength of 8,210 pounds, the chain is built to handle higher loads common on larger displacement bikes and ATVs.
• Vehicle specific fit: Offered in a 150 link length and with a clip-style master link, it is intended for direct replacement applications.

Who It's For

The DID 520 VX3 is best for riders of street bikes, dual-sport or enduro machines, and many ATVs up to 800cc who want a measurable step up in rigidity and seal performance over the VX2. Mechanics and experienced home wrenchers will appreciate the predictable fit and familiar installation process.

It is not for those who need non-standard link types or a factory rivet-style master link as some buyers have reported variations in the included master link. Riders on very small-swept commuter bikes that never see heavy loads can also find the VX3 overkill for their needs.

Pros & Cons

Pros

• Improved throttle response from the Direct Energy Transfer design.
• Strong average tensile rating of 8,210 pounds for heavier use cases.
• Better X-ring retention and seal durability compared with the previous VX2 design.
• Fits many applications up to 800cc and is straightforward to install.

Cons

• Some buyers report inconsistency about the inclusion of a clip-style master link, so check the package on receipt.
