DID 520ERT3-114 Gold 114 Link High Performance Racing Chain - Durable

In this review the DID 520ERT3-114 is evaluated for riders who demand a lightweight, high performance racing chain and expect improved shock resistance over older designs. The bottom line: this chain is aimed at serious motocross and off-road riders who want a chain that delivers a measurable jump in anti-shock performance and tensile strength without added weight. The review focuses on build details, real-world tradeoffs and the practical issue of missing hardware reported by some buyers.

Key Features

• 25% greater anti-shock: The ERT3 design offers noticeably better absorption of impact loads than the prior generation, which helps protect drivetrain components under hard use.
• 5% higher tensile strength: With an improved tensile rating over ERT2, the chain reduces the risk of catastrophic failure in aggressive riding situations.
• SDH pin treatment: The exclusive hard chromium carbide surface on the pin combines extreme surface hardness with a softer core to resist shock and minimize brittle failure.
• Cold-formed solid bushings: Solid bushings are cold-formed for a smooth, round surface that improves wear life and keeps engagement with sprockets consistent.
• Lightweight without compromise: The chain achieves higher performance metrics without increasing weight, keeping rotational mass down for quicker throttle response.
• Clip-style master link included: The package is listed with a clip-style RJ connecting link for field service and quick installation, though some buyers report missing links.

Who It's For

The DID 520ERT3-114 is best for motocross racers, enduro riders and anyone running a 520 chain spec who wants a step up in shock resistance and tensile strength while keeping weight low. Its construction details appeal to riders who push hard and need a chain that resists wear and absorbs impacts from jumps and rough terrain.

Riders who prioritize long-term low-maintenance sealed chains (O-ring or X-ring) or who require an included spare master link in the box should consider alternatives or verify contents before installation, as several customers have noted the master link was missing from their shipment.

Pros & Cons

Pros

• Improved anti-shock performance for aggressive riding and jump landings.
• Higher tensile strength without added weight improves reliability under load.
• Hard-treated SDH pins and solid bushings deliver strong wear resistance and a smooth interface with sprockets.
• Gold finish gives a high-quality look praised by buyers.

Cons

• Some customers report inconsistent durability in real use, with at least one reporting a short service life.
• Several buyers have noted the master clip-style link was missing on receipt, which can be an installation inconvenience.

Our Verdict

The DID 520ERT3-114 is a strong choice for racers and aggressive riders who want better anti-shock performance and slightly higher tensile strength without added weight. It provides solid construction with SDH pin treatment and cold-formed bushings that deliver good wear life, though buyers should confirm the master link is included and be aware of some mixed durability reports. Overall it represents good value for performance-focused drivetrain upgrades.

Frequently Asked Questions

Does the chain come with a master link?
It is listed as including a clip-style RJ master link, but some customers have reported receiving the chain without the link, so verify contents on delivery.

Is this an O-ring chain?
No, the ERT3 is a non-O-ring racing chain designed for lower drag and easier maintenance in racing environments.

Will it fit my bike?
It is a 520 pitch chain with 114 links; fitment depends on your bike's sprocket and required link count, so check your OEM spec or chain length before purchase.
