Voltage Regulator Rectifier - RM30325
Honda CB 600, CB 1000, CBF 1000, CBR 1000, NC 700 and NSA-DN01 - 2008-2016
This is a brand new aftermarket voltage regulator rectifier, supplied as a direct replacement for the original charging system regulator fitted to the Honda CB 600, CB 1000, CBF 1000, CBR 1000, NC 700 and NSA-DN01 built between 2008 and 2016. It arrives ready to fit: plug-and-play, direct fit, easy installation, with no assembly required.
The regulator rectifier is the component that turns the alternating current produced by the stator into the direct current your battery and electrical system need, and holds that output at a safe, steady voltage. This unit is built with a higher grade of electrical component than the original, and the quality exceeds the OEM equipment. Every unit is tested before it is shipped. All item pictures are accurate - if in doubt, do not hesitate to compare our item against your original part.

Frequently Asked Questions
Will this fit without modification?
Yes. This is a direct, plug-and-play replacement for the original regulator on the listed Honda models. It uses the same two plugs and five pins as the factory unit, and the two mounting holes sit 74 mm apart centre to centre. Nothing needs cutting or splicing. Before ordering, check the OEM number on your existing regulator against the cross reference table above and compare the shape of the part against the photographs.
What is included?
One brand new voltage regulator rectifier, part number RM30325, with the two factory-pattern plugs already fitted. No assembly is required and every unit is tested before it is dispatched.
How do I know my old regulator has failed?
With the engine running, a working charging system should show at least 14.5 V +/- 0.5 V at the battery terminals. A reading that stays down at resting battery voltage, or one that runs well above 15 V and boils the battery, points at the regulator rectifier. Other common symptoms are a battery that goes flat overnight, headlights that brighten and dim with engine speed, and melted or discoloured connector pins at the regulator plug.
How much output can this unit handle?
It is rated for a maximum charging current of 50 A / 500 W and holds open circuit voltage below 15 V, so it copes comfortably with the standard output of these Honda charging systems. The operating temperature range is -20°C to 85°C. Mount it in its original airflow position so it can shed heat properly.
