Frequently Asked Questions

Q: Does this sprocket include mounting hardware?
A: No, mounting hardware is not included; always inspect your existing retaining hardware and replace it if showing signs of wear.

Q: How do the self-cleaning mud grooves help maintenance?
A: They channel mud and dirt away from the tooth roots, preventing accelerated chain stretching and premature sprocket hook wear.

Expert Pro-Tip: When changing a 420 pitch front sprocket on mini bikes, always check your chain tension and alignment. Too tight of a chain puts excessive load on the countershaft seal and bearing, leading to premature oil leaks.
