FAQs
What chain size does this sprocket require?

Can I use this with a 520 or 530 chain?

How many teeth does this sprocket have?

Troubleshooting
Sprocket does not seat flush against the hub
Verify the hub internal diameter is exactly 125 mm and check for debris or old sealant residue on the mounting surface.
Excessive noise during operation
Ensure the chain pitch is exactly 525 and that the sprocket is aligned with the front drive sprocket.
Mounting bolts feel loose
Confirm that you are using 10.5 mm diameter bolts and consider using a thread-locking compound on the bolt threads.

Setup, Compatibility & Care
To ensure proper installation, verify that your motorcycle hub has an internal diameter of 125 mm and a hole distance of 150 mm. Use high-grade 10.5 mm flat-head bolts as specified to prevent wobble. Always cross-tighten the six bolts in an alternating pattern to ensure even pressure distribution. For care, regularly inspect the sprocket teeth for signs of hooking or excessive wear, and clean the sprocket assembly every time you perform routine chain maintenance. If you notice any metal shavings or unusual grinding noises, inspect the bolt security immediately.
