NZ-3 420 G/B
D.I.D's exclusive SDH pin treatment is the secret behind the superior performance of our NZ Series chains. This hi-tech pin treatment forms an extremely hard chromium carbide layer on the pins 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.

NZ-3 428 G/B
D.I.D's exclusive SDH pin treatment is the secret behind the superior performance of our NZ Series chains. This hi-tech pin treatment forms an extremely hard chromium carbide layer on the pins 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.

ATV 520 G/G
520ATV Was Designed Specifically for Quad Racing. 520ATV chain features the same low friction long wearing X-Ring technology as our VX, ZVM-X, ZLV, and ERV chains. Special steel alloy is used to provide extra strength required for Quad racing.

ERT2 520 G/G
D.I.D ER chain is designed exclusively for racing. 520ERT2 is used by the top factory Supercross and Motocross Teams. D.I.D's exclusive SDH pin treatment is the secret behind the superior performance of our 520ERT2 chains. This hi-tech pin treatment forms an extremely hard chromium carbide layer on the pins 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.

VT2 520 G/B
For offroad applications where a sealed chain is preferred, D.I.D's 520VT2 X-Ring® chain provides excellent low friction high performance. X-Ring® chain has 1.5 to 2 times greater wear resistance than standard O-Ring chain.

ERV3 520 G/G
D.I.D's High Performance Exclusive Racing Chain for Enduros and Desert. D.I.D X-RING® IS THE WORLD’S LOWEST FRICTION CHAIN. D.I.D’s PATENTED X-Ring construction reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting action of the X-Ring disperses the pressure and minimizes power loss.
