 Note that all stators make nearly their full power by 1400 RPM, which is approximately idle speed.  Kawasaki lists the stock alternator as being 17A at 10k RPM (or 238W at 14V), although this was not borne out by Electrosport's testing -- they say that the output curve is essentially flat above 6k RPM.
-No information has been collected on how much power the bike requires while running.  This information is necessary to accurately determine the actual power overhead available.  Common wisdom is that there's about 60W overhead available for accessories (lights, heated clothing, etc.) with a stock stator, which would imply that the bike needs about 120W to run.  IanJ is planning on gathering this information, but it's not currently a priority.

Forum posts have led some riders to surmise that there may be a somewhat higher electrical overhead, in the range of 70-90W, but the only way you can find out for sure is to install whatever accessories you're thinking about, put in a [[Installing a voltmeter|voltmeter]], and keep an eye on it.
 Electrosport reports that the ESG110 stator can be installed without modifications to the engine case, although it does not come with the correct connector, and will require cutting and soldering to get the stock connector swapped on.  The ESG636 can be installed in the Ninja 250's case, but it will "require some machining of the case."  More-specific information isn't available at this time.

 For the time being, a stator swap should be considered an expert-level modification, not suitable for most mechanics.  If you're comfortable with soldering and have access to heat-shrink tubing (electrical tape is '''not''' an acceptable insulator for this job), and are capable of jobs such as a valve adjustment, you have the skill to swap in the ESG110.  If you're willing to commit your engine cover to having at least 4mm machined off the stator mount-points, the ESG636 should be achievable.  If considering either modification, contact Electrosport directly for more-specific fitment information.
 This FAQ article should not be considered authoritative on the matter of stator installation.
