The DID 520 NZ Chain is a proven, non-sealed drive chain designed for riders who want crisp power transfer and low rotating mass—especially on vintage and lower-displacement off-road motorcycles. Compared to many OEM non-sealed chains, the 520NZ delivers a stronger, more consistent feel with construction details aimed at improving durability and extending chain life.
If you ride in conditions where you prefer the simplicity and efficiency of a non-sealed chain, the 520 NZ is a great upgrade. Its DHA pin treatment forms a hard chromium-carbide layer on the pin surface to help reduce wear, while quad-stake riveted pins and solid bushings improve overall strength and reliability under load.
Key features:
✅ DHA pin treatment (hard chromium-carbide layer) for improved wear resistance
✅ Quad-stake riveted pins and solid bushings for strength and longer service life
✅ Clip master link included for practical installation and servicing
Benefits of use:
🔹 Better performance than many OEM non-sealed chains for vintage and smaller-displacement setups
🔹 Reliable strength under riding load thanks to reinforced pin/bushing construction
🔹 Easy maintenance and fitment with a 520 size and clip-style master link
