D.I.D is the number one motorcycle chain in the world. D.I.D chains are used by factory races teams from all manufacturers in race series everywhere.
The All New D.I.D 520DZ2 is the best value in a lightweight, high-performance chain designed for motocross racing.
Designed for off-road riding and motocross.
The DZ2 has twice the lifespan of the previous DZ.
SDH pin treatment - hard chromium-carbide layer formed on pin surface for exceptional strength and wear resistance.
Flexible inner soft core absorbs shock.
Rated for up to a 450cc motocross bike.
Includes a clip-style master link.
Notes: DZ and DZ2 Connecting Links are not interchangeable. Non-sealed chains require more regular maintenance than sealed (O-ring, X-ring) versions and are mainly recommended for off-road use.
D.I.D's exclusive SDH (Super DH) pin treatment is the secret behind the superior performance of the DZ Series chains. This high-tech pin treatment forms an extremely hard chromium carbide layer on the pin's surface while maintaining a soft inner core. SDH treated pins have extreme impact strength while maintaining outstanding shock absorption. This treatment creates a chain with anti-oxidation properties and superior wear resistance against invasion of hard foreign materials.
