Frequently Asked Questions

What is offset and why does it matter?

Offset adjusts the sprocket position on the shaft to align the 530 chain with your rear sprocket without frame modification. This 0.500 in offset centers the chain for most builds.

Can I use this on a stock belt-drive bike?

No — this transmission sprocket is designed for conversion builds switching from belt to 530 chain. Stock bikes retain the factory belt drive.

Is this sprocket hardened against wear?

Yes. Carburized steel is hardened to resist both impact load and tooth wear, extending sprocket life in high-demand applications.

Will this fit my specific V-twin?

This part fits V-twin motorcycles in belt-to-chain conversions. Confirm the 25-tooth count and 0.500 in offset match your rear sprocket and frame geometry before purchase.
