ESG922 is a high quality stator that replaces the OEM stator in the Aprilia RSV 1000 Mille between 1999 and 2003 as well as the RSV1000 Tuono from 2002 to 2005. ElectroSport uses a modern stator core as a base and winds it with the highest grade copper wire on modern winding machines. The winding configuration we optimized for this Aprilia model which results in a cooler running winding for vastly improved reliability. The low magnetic losses in the core coupled with the reconfigured winding result in a very efficient stator that has a flat output across the RPM range. We add the best grade lead wires that offer super abrasion resistant insulation, low electrical resistance and a high tolerance for heat. We add high quality rubber seals, the best insulation coatings and connectors. ESG922 is superior to the OEM stator in both performance and reliability and is a plug in replacement for the original unit. Like all stators that are manufactured by ElectroSport, our ESG922 also comes with a full one year warranty.
