Voltage Regulator Rectifier for Kawasaki Ninja ZX-6R - RM30321
Kawasaki Ninja ZX-6R / ZX6R - 2007 and 2008
A brand new aftermarket voltage regulator rectifier, supplied as a direct replacement to the original unit on the 2007 and 2008 Kawasaki Ninja ZX-6R. The regulator rectifier does two jobs at once: it converts the alternating current produced by the stator into the direct current the bike runs on, and it holds the charging voltage at a safe level so the battery and electronics are neither undercharged nor cooked. When it fails the consequences spread quickly - a flat battery, boiling electrolyte, blown bulbs or a bike that will not restart after a ride.
This unit uses a higher grade of electric components together with an improved heat sink and charging capability, which matters on a sports bike where the regulator sits in a tight, hot part of the chassis and heat is the usual cause of failure. It regulates to a minimum 14.5 V +/- 0.5 V with an open circuit voltage below 15 V, handles up to 50 A or 500 W and is rated for operation from -20°C to 85°C. Fitting is plug-and-play with no assembly required: two plugs carrying six pins and six wires connect straight to the original harness, and the 80 mm fixation hole spacing matches the standard mount. The manufacturer states the quality exceeds the OEM equipment and all products shipped are tested.

Frequently Asked Questions
Will it fit without modification?
Yes. It is a direct fit for the 2007 and 2008 ZX-6R, with two plugs, six pins and six wires matching the original connectors, and 80 mm between the fixation holes to suit the standard mounting bracket. No assembly, cutting or splicing is required. Confirm your original part number is 21066-0025 before ordering.
What is supplied?
One voltage regulator rectifier with its two fitted plugs and wiring leads, one 135 mm and one 250 mm, ready to connect to the bike's harness. The unit is tested before it is shipped.
How do I know the old regulator rectifier has failed?
Measure the voltage at the battery with the engine running. A healthy system should be charging to around 14.5 V; a reading that stays close to battery voltage means it is not charging, while a reading above roughly 15 V means it is overcharging and will damage the battery. Other signs are a battery that goes flat overnight, dimming or flickering lights, repeatedly blown bulbs, a bike that will not restart when warm, and a regulator body that is scorched, discoloured or has melted connectors.
Why does the improved heat sink matter?
A regulator rectifier works by turning surplus charging output into heat, so the ability to shed that heat is what determines how long it lasts. This unit has an improved heat sink and charging capability and is rated for continuous operation from -20°C up to 85°C, handling up to 50 A or 500 W. When fitting, make sure it sits in its original airflow position and that the connectors are clean and tight, since a corroded connection generates extra heat and is a common cause of repeat failures.
