Decoding the 520 Chain: A Comprehensive Guide

Motorcycle chains are crucial for power transmission, and understanding their specifications is vital for performance and longevity. The 520 chain is a common size, but its variations and compatibility with other components, such as 428 sprockets, often cause confusion. This guide will clarify the intricacies of 520 chains, their types, and their compatibility issues. Discussions on online forums like www.Chinariders.net highlight the common questions and concerns surrounding these components.

Understanding 520 Chain Specifications

The “520” designation refers to the chain’s pitch and roller dimensions. The pitch, the distance between the centers of two consecutive rollers, is 5/8 inch (15.875 mm). The roller width is approximately 0.25 inches (6.35 mm), and the roller diameter is roughly 0.4 inches (10.16 mm). These dimensions are standardized, ensuring interchangeability within the 520 chain family. However, manufacturers like MPM Motorsports (mpm-motorsports.com) offer a range of 520 chains with varying materials and features.

Technical Features Comparison Table

The following table compares key technical features of different 520 chains, as discussed on sites like www.usarollerchain.com and hzpt.com. Note that specific values can vary based on manufacturer and material.

Feature	Standard Chain	O-Ring Chain	X-Ring Chain
Pitch (inches)	0.625	0.625	0.625
Roller Width (in)	0.25	0.25	0.25
Roller Diameter (in)	0.40	0.40	0.40
Sealing	None	O-rings	X-rings
Friction	High	Medium	Low
Lubrication	Frequent	Less Frequent	Infrequent
Durability	Lower	Medium	High
Cost	Lower	Medium	Higher

Different Types of 520 Chains

Various 520 chains cater to different needs and applications. The choice depends on factors like riding style, budget, and desired lifespan. This is a common topic of discussion on forums like www.Chinariders.net.

Chain Type	Description	Advantages	Disadvantages
Standard	Basic design without sealing elements.	Low cost	Requires frequent lubrication, lower durability
O-Ring	Includes O-rings between link plates to retain lubricant.	Improved lubrication, extended lifespan	Slightly higher cost
X-Ring	Uses X-rings for superior sealing and reduced friction compared to O-rings.	Best sealing, longest lifespan, less maintenance	Highest cost
Z-Ring	Similar to X-ring but with a different design for even better sealing.	Superior sealing, extended lifespan	Highest cost, limited availability

520 Chain and 428 Sprocket Compatibility

While a 520 chain can be used with a 428 sprocket, it’s not recommended. The larger 520 chain puts extra stress on the smaller 428 sprocket, leading to premature wear. This incompatibility is frequently addressed on hzpt.com. Choosing matching chain and sprocket sizes ensures optimal performance and longevity.

Conclusion

Choosing the right motorcycle chain involves understanding the nuances of pitch, roller dimensions, and sealing mechanisms. The 520 chain offers various options, each with its strengths and weaknesses. Proper selection, considering factors like riding style and budget, is crucial for optimal performance and extended lifespan. Always ensure chain and sprocket compatibility to avoid premature wear and potential damage.

FAQs

1. What is the difference between a 428 and a 520 chain?

The main difference lies in their dimensions. A 520 chain has a larger pitch and roller dimensions than a 428 chain, making it stronger and more durable but also heavier.

2. Can I reuse a 428 chain with new sprockets?

It depends on the chain’s condition. If the chain shows significant wear (stretching, corrosion), it should be replaced. A slightly used chain might be usable, but inspect it carefully.

3. Which 520 chain type is best?

The best type depends on your needs and budget. Standard chains are cheapest but require more maintenance. O-ring and X-ring chains offer better sealing and longevity but cost more.

4. Are 520 chains always heavier than 428 chains?

For the same length, a 520 chain will usually be heavier due to its larger components. However, a shorter 520 chain might weigh less than a longer 428 chain.

5. What happens if I use a 520 chain on a 428 sprocket?

Using a 520 chain with a 428 sprocket will cause excessive wear and tear on the sprocket due to the mismatch in dimensions and increased stress. This can lead to premature failure of both components.
