Frequently Asked Questions
What is this sprocket used for?
Transmission sprockets are used in belt-to-chain conversion builds. The 25-tooth count provides proper gear ratio adjustment when switching from OEM belt drive to 530 chain.
Does this come with mounting hardware?
This is the sprocket only. You will need spline bolts and a retaining nut appropriate for your transmission shaft.
How do I know if I need a standard or offset sprocket?
Standard offset works with most conversions. Offset versions adjust alignment to match your rear sprocket. Consult your conversion kit instructions or a technician before ordering.
Is this stainless steel?
No — this is carburized steel with a black oxide finish, which provides excellent wear resistance. The black oxide protects against corrosion.
Will this fit my specific Harley or Indian model?
This fits V-twin engines in belt-to-chain conversion builds. Verify your conversion kit part number and transmission shaft spline count before ordering.
