Product Information
Full details
The DID NZ3 420-pitch transmission chain is designed for motocross riders and racing enthusiasts who prioritize power delivery and acceleration over long-term weather resistance. Featuring a lightweight, O-ring-free construction and advanced SDH-treated pins, this chain minimizes rotating mass to improve bike agility and responsiveness. While its gold and black finish offers a premium look, users should be aware that the lack of O-ring seals requires more frequent maintenance and lubrication to prevent premature wear in harsh conditions.

FAQs
Does this chain come with a master link?
Yes, it includes a split link (clip type) for tool-free installation.
Can I use this chain for adventure riding or long-distance touring?
While technically possible, this chain is designed for racing. For touring, an O-ring or X-ring chain is recommended for better longevity.
How often should I lubricate the NZ3 chain?
You should lubricate it after every ride or race session to maintain performance and prevent oxidation.
Is the 134-link length adjustable?
Yes, you can remove links using a standard chain breaker tool to achieve the exact length required for your specific motorcycle model.
Why is this chain lighter than sealed chains?
By removing the O-ring seals, we eliminate the rubber weight and the drag associated with the seal friction, resulting in a lighter, faster-spinning chain.
Troubleshooting
Chain making excessive clicking noises
Check chain tension; it is likely too loose and hitting the chain guide or swingarm.
Stiff or frozen links
Clean the chain thoroughly with a dedicated chain cleaner and apply penetrant lubricant to the stiff link, then work it back and forth until it moves freely.
Chain frequently becomes loose
This is a sign of chain elongation or sprocket wear. Verify that the chain is correctly lubed and check sprockets for shark-fin shaped teeth.
Pros and Cons
Pros
- Significantly reduces rotating mass for better acceleration
- Easy to install and adjust with the included clip connector
- High-tensile strength for demanding race environments
- Attractive gold and black aesthetic
- Low-friction design maximizes power transfer
Cons
- Requires more frequent cleaning and lubrication than sealed chains
- Not optimized for long-distance durability in muddy or wet environments
- Standard clip link may require safety wiring for extreme racing conditions
Setup, Compatibility & Care
This chain is a 420-pitch, 134-link model. Before installation, ensure your motorcycle sprockets are also 420-pitch and show no signs of "hooked" or worn teeth, as installing a new chain on worn sprockets will cause premature failure of the chain pins.
- Remove the old chain and check sprocket alignment.
- Route the new chain over the sprockets; if the length is too long, use a chain breaker tool to remove excess links.
- Connect the ends using the provided clip link, ensuring the clip's closed end faces the direction of travel.
- Adjust tension according to your motorcycle manufacturer's specifications—typically 25-35mm of chain slack.
- Apply lubricant to the rollers and side plates to maintain the protective film.
- Regularly inspect the chain for stiff links or elongated pins every 5-10 operating hours.
