520DZ-98 Gold 98 Link High Performance DZ2 Chain - Racing Ready

In this review the 520DZ2 is examined as a budget-friendly, high-performance non-sealed racing chain aimed at riders who push through rough motocross conditions. The bottom line: the chain is best for ATVs and motorcycles up to 450cc that need strong, reliable drive performance without the premium price of sealed chains. Its standout trait is a heavy-duty 7870 lb tensile strength and SDH technology that keeps the chain durable on demanding tracks, while the gold outer plates give a premium look.

Key Features

• High tensile strength: The 7870 lb rating provides confidence under hard acceleration and heavy loads on motocross tracks.
• SDH technology: Designed for grueling MX use, the SDH treatment improves wear resistance and long-term durability in aggressive riding conditions.
• Non-sealed design: The open link construction is simpler to clean and service after muddy, wet rides, which can save time between races.
• Visual finish: Gold outer plates with black inner links offer a premium appearance that fits well on show-ready builds or restored bikes.
• Compatibility: Rated for ATVs and motorcycles up to 450cc, making it suitable for a wide range of off-road and trail machines.
• Connecting link included: A clip style master connecting link is supplied for straightforward installation and field repairs.

Who It's For

The 520DZ2 is aimed at motocross racers, weekend trail riders, and budget-conscious enthusiasts who need a tough replacement chain that stands up to jumps, whoops, and wet conditions without costing as much as sealed race chains. Riders who value a sturdy tensile rating and a durable coating will appreciate this chain's resilience and finish.

Those who require a sealed O-ring chain for extended lubrication retention and lower long-term maintenance should look elsewhere, as this model is a non-sealed design and lacks O-ring protection. Also, riders of machines over 450cc should choose a chain rated for higher displacement and load.

Pros & Cons

Pros

• Strong 7870 lb tensile rating gives durable performance under heavy use.
• SDH technology and finish resist wear and help prevent rusting of outer links.
• Attractive gold and black finish improves the visual appeal of the drivetrain.
• Clip style master connecting link makes installation and on-trail repairs straightforward.

Cons

• Non-sealed design means less protection from grit and less retained lubrication compared with O-ring chains.
• Some customers expected an O-ring chain and noted mixed messaging about that feature.
