FAQs
Can I use this chain on a street motorcycle?
While the 520 ERV7 is designed for racing, it can be used on street bikes if the motorcycle is compatible with a 520-pitch chain and meets the power output requirements. Note that it requires more frequent maintenance than standard street chains.
What is the benefit of the ZJ rivet link?
The ZJ rivet link provides the highest level of security for the chain loop, preventing the master link from coming undone under the extreme stresses of track racing.
Does this chain come pre-lubricated?
Yes, it comes with factory-applied high-performance lubricant inside the seal rollers. Do not wash this out before the first use.
Is this chain compatible with non-DID sprockets?
Yes, as long as the sprockets are designed for a 520-pitch chain, the ERV7 is compatible.
How often should I adjust the tension?
Racing chains experience higher stress. Inspect the tension before every track session or ride.
Troubleshooting
Chain appears to be too long or too short
The 118-link length can be shortened by removing excess links using a chain breaker tool. If it is too short, consult your bike's service manual to confirm if a longer chain is required for your specific sprocket configuration.
Excessive noise or vibration during operation
Check your chain tension to ensure it meets the manufacturer's specification. Also, inspect sprockets for "hooked" or worn teeth, as a new chain will wear rapidly against old, damaged sprockets.
Pros and Cons
Pros
- Race-proven durability in MotoGP and SBK
- Extremely lightweight design improves bike agility
- High breaking load handles high-horsepower outputs
- Gold finish resists rust and wear effectively
Cons
- Requires specialized riveting tool for installation
- Frequent maintenance required compared to street-only chains
- Not intended for heavy-duty off-road or dual-sport use
Setup, Compatibility & Care
- Compatibility: Ensure your motorcycle utilizes a 520 pitch sprocket setup. This chain is 118 links long; check your swingarm geometry to ensure this length provides sufficient adjustment room.
- Installation: Installation must be performed using a high-quality chain riveting tool to flare the pins of the ZJ master link properly. Do not attempt to use a clip-style master link for high-performance applications.
- Care: Clean the chain regularly with a non-petroleum based cleaner and apply a high-quality motorcycle chain lubricant specifically designed for O-ring or X-ring chains. Avoid using pressure washers directly on the link seals to prevent lubricant contamination.
