What Better: 520 or 525 Motorcycle Chain?

When comparing 520 vs 525 motorcycle chains, there are a few key differences to consider:

• Pitch – The 525 chain has a larger pitch (distance between pins) of 5.25mm vs 5.20mm on the 520 chain. This allows the 525 to handle more power.
• Strength – 525 chains can be built with thicker side plates and larger pin/roller diameters. This makes them stronger than 520 chains.
• Usage – 520 chains are very common on smaller displacement bikes under 600cc. 525 chains tend to be used on larger, more powerful motorcycles.
• Chainspeed – The 525 chain is capable of higher chainspeed operation due to the larger pitch and components.
• Wear – The thicker 525 chain generally lasts longer before stretching and wears slower compared to 520 chains.
• Weight – 525 chains weigh a bit more than 520 chains of the same length.
• Price – 525 chains cost more than their 520 counterparts.

In summary, 525 chains are designed for more torque and power compared to 520 chains. Their greater strength and durability make them ideal for high performance applications. However, 520 chains work well for lower displacement bikes. So consider your motorcycle’s power output when choosing.
