ESG791 is a very high quality stator that replaces the (unreliable) OEM stator in the Yamaha FZS600 Fazer models between 1998 and 2004 ElectroSport manufactures the ESG791 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 ESG791 to make the stator run much cooler which drastically improves reliability. With these changes our ESG791 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 ESG791 also comes with a full one year warranty.
