Specs At A Glance

Good To Know

Q: Can this regulator be used on a Polaris 550 Indy EVO 129? A: This regulator is listed for the 121 and 144 EVO tracks; if your 129 uses the same electrical setup and connector, it may work, but verify the original part number.

Q: How do I know this regulator is failing? A: If the battery does not hold a charge, lights flicker, or the engine misfires at high RPM, test the regulator's output voltage. A reading above 15 volts or below 13 volts suggests replacement is needed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
