ESC392 is a complete high quality replacement stator for the Yamaha YZ85 between the years 2002 and 2011. Our ESC392 is a complete unit that comes on a new base plate, complete with pulser coil, high quality wiring, rubber seal and connector and is therefore a breeze to install. We improved upon the OEM stator by choosing a much higher grade copper wire which translates into a lower winding temperature and much improved reliability. ESC392 offers superior quality compared to the OEM Yamaha stator and it comes with a full one year warranty.
