ElectroSport Regulator/Rectifier - ESR025

ESR025 is a regulator that replaces the internal regulator inside Nippon Denso alternators.

This alternator is commonly used on certain Suzuki GSX-R models, on Yamaha FJ models, and Kawasaki Ninja models between 1984 up to now.

Even though ESR025 looks different compared to the stock regulator, it fits perfectly, has MUCH better heatsinking capability and incorporates a thermal overload circuit. This circuit is important because it shuts down the regulator if the alternator rotor is shorted, a problem that is very common now. Typically the OEM voltage regulator dies when the rotor shorts out. The ESR025 voltage regulator is superior to the stock one and will most likely outlast the alternator it is installed in!

ESR025 comes with a full one year warranty like all other components manufactured by ElectroSport.

Features:

• High quality and better-than-OEM regulator/rectifier
• We built these stators using the latest technology in regulator circuitry, and use a very efficient heat sink to get rid of the heat quickly and efficiently
• Controls the output voltage very accurately resulting in a perfect charge rate for your battery across the RPM range
• Thanks to the modern power circuits it runs much cooler than the OEM unit which drastically improves reliability compared to stock
• 1-year manufacturer's warranty
