A brand new voltage regulator rectifier for the Kawasaki KLX 650, supplied as a direct replacement for the original unit. It is plug-and-play and direct fit, with no assembly required.
The unit takes the alternating current from the stator and converts it into the regulated direct current the battery and the rest of the bike need, holding a minimum charging voltage of 14.5 V +/- 0.5 V. RMSTATOR uses a higher grade of electrical components in this part and states that the quality exceeds the OEM equipment. All units are tested before shipping.

Frequently Asked Questions
Will this fit without modification?
Yes. On the Kawasaki KLX 650 from 1993 to 1996 this is a direct replacement for the original unit, using the same single five-pin plug and the same 55 mm fixing hole spacing. It mounts and connects with the existing hardware and harness.
What is included?
The voltage regulator rectifier itself. RMSTATOR does not list any additional items in the box for this part number.
How do I tell my old regulator rectifier has failed?
With the engine running and warm, measure across the battery terminals. The charging system should be pulling the voltage up towards the 14.5 V +/- 0.5 V this unit is rated to hold. If the voltage sits at rest level the battery is not being charged; if it climbs beyond 15 V the regulator has failed open and is overcharging, which will cook the battery and take out bulbs. Check the stator output too, so the real fault is found before parts are changed.
Does the OEM number need to match?
It is the most reliable check. This unit cross references Kawasaki 21066-1091. If that number is on the label of the regulator currently fitted to your KLX 650, this is the correct replacement.
