ESG381 is a high quality replacement stator for the OEM stator in the Suzuki VZR1800 / M109R Boulevard (06-15) models. ElectroSport manufactures the ESG381 stator using a high quality core and the highest grade copper wire for the windings. The reconfigured winding configuration from stock and the high magnetic conductivity of the new stator core result in vastly improved efficiency compared to stock. Our ESG381 stator offers a flat output across the RPM range and also runs 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 making this stator a plug in replacement of the OEM unit. Like all stators manufactured by ElectroSport, this ESG381 also comes with a full one year warranty.
