DID 520DZ-114 Gold 114 Link High Performance DZ2 Chain - MX Ready

In this review the DID 520DZ2 chain is evaluated as a budget-friendly, performance-minded option for motocross and powersports riders who need a durable non-sealed chain. The bottom line: it is best for riders on ATVs or motorcycles up to 450cc who want a strong, race-capable chain with a premium look without the premium price; the single biggest reason to buy is its 7,870 pound tensile strength combined with SDH durability for grueling track conditions.

Key Features

• High tensile strength: The chain is rated at 7,870 lb tensile strength, providing confidence under heavy loads and aggressive riding.
• Race-oriented design: The DZ2 series uses SDH technology to handle the repeated shock and abrasion of motocross tracks, improving durability.
• Non-sealed construction: As a non-O-ring racing chain, it reduces friction points for competitive use and easier maintenance between events.
• ATV and motorcycle compatibility: Sized and rated for machines up to 450cc, making it suitable for a wide range of off-road and trail bikes.
• Visual finish: Gold outer plates with black inner links give a premium, finished look that many riders noted fit and looks great on their bikes.
• Connecting link included: A clip style master connecting link is supplied, allowing straightforward installation and removal without special tools.

Who It's For

The DID 520DZ2 is aimed at local motocross racers, club riders, and weekend warriors running ATVs or motorcycles up to 450cc who want a strong, race-capable chain on a budget. Riders who value tensile strength, a sturdy SDH build for rough track conditions, and a striking gold-and-black finish will appreciate this chain.

Riders who require O-ring or fully sealed chains for long-service street use should look elsewhere, since this model is a non-sealed racing chain. Also, those who demand factory-sealed lubrication for extended maintenance intervals may prefer a sealed chain alternative.
