ESG650 is a high quality HIGH OUTPUT stator that replaces the OEM stator in the Yamaha XV650 V-Star (Star XV650) models from 1997 to 2003. ElectroSport manufactures the ESG650 stator using the highest grade copper windings and a modern stator core. We optimized the winding configuration to offer much better output across the RPM range while at the same time running much cooler than the OEM stator. Output of this stator has increased 25% compared to the stock stator which is a substantial improvement that will allow for a lot more electrical accessories to be added. We install high grade lead wires that have super chafe resistant insulation and is very heat tolerant. We add high quality rubber seals, the best insulation coatings and connectors to make this part superior to the OEM unit. Our ESG650 stator offers the best performance across the RPM range and superior reliability. Like all stator manufactured by ElectroSport this ESG650 also comes with a full one year warranty. Power Output: 275W @ 3500RPM* *The actual power output varies depending on the configuration and condition of the charging system. Actual performance is typically within +/- 5% of this value. Our tests of the OEM stator and flywheel show a maximum output of 210W @ 3500RPM
