This high power stator kit is designed to TRIPLE the charging output on the KTM models for which the kit is listed. It replaces the OEM single split wound stator with a modern 3-Phase stator and then feeds into a regulator/rectifier through the included wiring harness. Expect output to go from a stock 80W (total) to about 250W. Our ESK145 stator kit is ready to install, it comes with detailed instructions and is covered with a full one year warranty.
