ESG836 is a high quality stator that replaces the OEM stator in the Yamaha TMAX500 between 2001 and 2011. ElectroSport uses a modern stator core as a base and winds it with the highest grade copper wire on modern winding machines. 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 and is much cooler running. 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. ESG836 is superior to the OEM stator in both performance and reliability and is a plug in replacement for the original Yamaha unit. Like all stators that are manufactured by ElectroSport, our ESG836 also comes with a full one year warranty.
