DID 520DZ-116 Gold 116 Link High Performance DZ2 Chain - Racing Ready

In this review the DID 520DZ2 chain is examined for riders who want a budget-friendly, race-capable drive chain. The bottom line: it is a high-performance, non-sealed racing chain built to stand up to rough motocross use while keeping cost low. The 520DZ2's key selling point is its SDH technology and a 7,870 lb tensile strength rating that targets ATVs and motorcycles up to 450cc, making it an attractive option for weekend racers and club riders who need durable performance without paying for a sealed O-ring design.

Key Features

• Performance construction: SDH technology provides improved wear resistance and strength for demanding motocross tracks.
• Tensile rating: A 7,870 lb tensile strength means the chain is rated for ATVs and motorcycles up to 450cc, instilling confidence under load.
• Non-sealed design: The non-O-ring build lowers cost and simplifies maintenance for riders who prefer frequent cleaning and relubrication.
• Finish and appearance: Gold outer plates with black inner links give a premium look that stands out on the bike while resisting visible corrosion.
• Connecting link included: A clip style master connecting link ships with the chain for straightforward installation in the field or shop.

Who It's For

The 520DZ2 is aimed at local motocross competitors, club racers, and recreational riders who want a durable, race-oriented chain without the added cost of sealed O-rings. It suits owners of dirt bikes and ATVs up to 450cc who perform regular maintenance and prefer the simplicity of a non-sealed chain.

Riders who need a fully sealed, maintenance-light chain or who specifically require O-ring lubrication retention should look elsewhere; the 520DZ2 is deliberately a non-O-ring racing chain and will require more frequent care to maximize life in wet or muddy conditions.
