ESG110 is a high quality stator that replaces the OEM stator in the Kawasaki EX250 Ninja, EX500 Ninja, GPZ500, EL454, EL500 and EN500 models between the years 1985 and 2009 ElectroSport manufactures the ESG110 stator starting with a brand new stator core made of special material that has very low magnetic resistance. We use the highest grade copper wire for the windings which are installed using computer controlled winding machines for optimum results. Our lead wires are of very high quality and we chose a type that is abrasion and heat resistant. The rubber seals and connectors are an exact match for the original stator making this ESG110 a plug in replacement. With the top notch materials and design features chosen our ESG110 stator offers superior performance and reliability. Like all stators manufactured by ElectroSport this ESG110 stator also comes with a full one year warranty.
