These sprockets from DirtyBike Industries are OEM quality zinc coated hardened steel with beveled edges for smooth chain engagement.

NOTE!: Please be extremely careful when removing the 6 sprocket mounting bolts! They are thread locked in place and strip very easily. Use a quality hex driver tool and apply generous amounts of heat to the aluminum around the threads to loosen the bolts before attempting to remove them.
