ESG792 is a very high quality stator that replaces the unreliable OEM stator in the Yamaha YFZ - R1 models between 2002 and 2003. ElectroSport manufactures the ESG792 stator using a high quality core and the highest grade copper wire for the windings. The OEM stator is very unreliable in these bikes and ElectroSport developed the winding configuration for this ESG792 to make the stator run much cooler which drastically improves reliability. With these changes our ESG792 stator offers a perfect output across the wide RPM range. We install very high grade lead wires that feature heat and chafe resistant insulation and high quality rubber seals and insulation coatings making this stator a plug in replacement of the OEM unit. Like all stators manufactured by ElectroSport, this ESG792 also comes with a full one year warranty.
