The DID 420 NZ3 is part of the industry leading DID ER range designed exclusively for racing. The NZ3 chain is the latest evolution in DID's range on high performance, light weight, non-O-ring chain designed exclusively for Motorcross racing.
The NZ3 is further upgraded with Super Dai Hard (SDH) treated pin technology. The hi-tech SDH pins have an extremely hard chromium carbide surface while maintaining a soft inner core. This allows the pins to have a high impact strength combined with incredible shock absorbance further increasing the wear resistance of the NZ3.
