DID 520VX3-120 Steel VX Series X-Ring Chain - High Performance

In this review of the DID 520VX3-120 Steel High Performance VX Series X-Ring Chain, the bottom line is clear: this chain is for riders and mechanics who need a durable, well-fitting replacement chain that balances strength and everyday usability. The reviewer found it offers solid construction and straightforward installation, making it especially suitable for commuter bikes, off-road enduros, and anyone who wants reliable drivetrain performance without overspending. The most convincing reason to buy is its combination of reliable tensile strength and practical fit, which delivers dependable performance in routine and spirited riding.

Key Features

• Tensile strength: The chain lists an average tensile strength of 8,210 lbs, providing confidence under load for most street and off-road applications.
• X-ring sealing: The VX series X-ring design reduces internal friction and helps preserve lubrication, extending chain life compared with unsealed rollers.
• 120 links: The 120-link length offers flexibility to fit a wide range of motorcycle swingarm lengths without immediate need for additional links.
• Steel construction: Heavy-duty steel construction gives the chain a durable feel and consistent wear characteristics for long-term use.
• Connecting link: A connecting link is included to simplify installation, though customers report some variation in whether a clip-style master link is provided.

Who It's For

This chain is best for motorcyclists who want a robust, no-nonsense replacement chain that handles daily riding and occasional tougher use. It suits owners of commuter motorcycles, dual-sport and enduro riders who need a reliable part that fits well and installs without fuss.

Riders seeking the absolute lightest race-spec chain or those requiring a model with a guaranteed specific master link style should look elsewhere; some buyers noted inconsistency in the master link hardware, so if you need a particular clip or rivet master link type, confirm before purchase.
