Frequently Asked Questions

Q: Does this sprocket come with mounting hardware?
A: No, this package includes the rear aluminum sprocket only. Existing hardware can be reused, though checking bolt condition during installation is recommended.

Q: Is an aluminum sprocket suitable for off-road racing?
A: Yes, the 7075-T651 aluminum material with extra tempering provides the ideal balance of lightweight racing performance and enhanced wear resistance.
