ESG770 is a very high quality stator that replaces the OEM stator in the Yamaha YZF600R between the years 1995 and 2007 ElectroSport manufactures ESG770 using a high quality core and the highest grade copper wire for the windings. A slightly reconfigured winding configuration from stock and the high magnetic conductivity of the new stator core result in vastly improved efficiency compared to stock. Our ESG770 stator offers a flat output across the RPM range and it also runs much cooler than the stock stator, which drastically improves reliability. We install a superior quality pulser coil, very high grade lead wires that feature heat and chafe resistant insulation, high quality rubber seals and insulation coatings making this stator a plug in replacement of the OEM Yamaha stator. Like all stators manufactured by ElectroSport, this ESG770 also comes with a full one year warranty.
