The ESR552 is a high quality regulator/rectifier specifically designed to replace the unreliable OEM part on several Suzuki GSX-R models.
The ESR552 has a very efficient heat sink that keeps the temperature of the unit low. Internally, only the highest quality components are used for the circuits. The result is a very high quality product that is far superior to the OEM controller.
This regulator/rectifier precisely controls the output power and provides a stable charge to the battery over the entire speed range.
Note: Technically modified controllers are excluded from exchange!
