Definition
The "520" label refers to the chain family, not just the tooth count. The sprocket must match the chain pitch and the motorcycle application.
Knowledge base
What is a 520 sprocket?
A 520 sprocket is cut for 520 chain pitch. It only fits correctly when the chain, hub or spline pattern, offset, and bike fitment all match.
Practical use
520 sprockets are common on off-road bikes because they balance durability, parts availability, and gearing flexibility.
Material notes
Steel usually lasts longer. Aluminium can reduce rotating mass on rear applications, but wear life is shorter in harsh dirt use.
Common mistakes
- Matching only the tooth count and ignoring chain pitch.
- Assuming every 520 sprocket fits the same hub or spline pattern.
- Skipping offset and clearance checks after a chain conversion.
