Kawasaki Ninja 250? More Specifically 1988-2007? If it helps any here's a link
to the info on the Ninja 250 site concerning the original stator's output power vs. rpm compared to some aftermarket ones.. I've installed the ESG110 from Electrosport some time ago and it helped quite a bit with powering heated gear in the wintertime, however it's died since then so I've went back to the original stator.
