ESG780 is a very high quality stator that replaces the OEM stator in the Yamaha YFZ-R6 models between 1999 and 2002. ElectroSport manufactures the ESG780 stator using a high quality modern stator core and the highest grade copper wire for the windings. The reconfigured winding configuration and the high magnetic conductivity of the new stator core result in vastly improved efficiency compared to OEM Yamaha stator. Not only does our ESG780 stator offer a perfect output across the RPM range, it also runs much cooler than the stock stator which drastically improves reliability. We install very high grade lead wires that feature heat and chafe resistant insulation and high quality rubber seals and insulation coatings make this stator a plug in replacement for the OEM unit. Like all stators manufactured by ElectroSport, this ESG780 also comes with a full one year warranty.
