Part: Honda Regulator / Rectifier Combo Replacement - CB550F / CB550K / CB500K

Why You Need This: The charging systems on these old Hondas are not the best, and the weak points tend to be the outdated electronic components. The factory voltage regulator (limits total voltage to the battery) and rectifier (converts AC to DC) were not of the highest quality to begin with, and now after decades of use and abuse they're even worse off. We've managed to find an affordable drop-in Honda replacement regulator / rectifier combo kit. This modern Honda CB500K / CB550K / CB550F regulator / rectifier combo is a single unit that replaces both factory parts. This is the single best electrical upgrade you can do to your Honda next to our halogen H4 headlight.

Installation Tip: This unit replaces both the factory regulator and rectifier. Depending on the bike you are working on, this unit can be mounted under the side cover with the rest of the electrical components. The original regulator and rectifier can be unplugged from the wiring harness and the new one simply connected. The black, white, and green wires connect where the voltage regulator was connected to the harness.

Better than OEM
Super simple install. Just unplug the old reg/rec and plug new unit into existing connectors. Not hard to find a convenient place to mount the new unit. Now the battery stays fully charged, very important with electric start and the difficult cold starting nature of my CB550. Just like all the other items I have gotten from CMC, it is a top quality item!

Vintage Honda Lover
I have been replaced the old rec/reg stock part today with this new electronic combo version bc. I had esp. at city tours with stop-and-go traffic the problem of weak battery even after 2-3-days. And low battery for this type of Honda bike is very bad since I could not run the engine anymore. Installation of the new part was easy and the first results are promising. 1. the voltage is controlled w/o headlight between 12,8 (idled)-14,5 V ( 5kpm) 2.voltage is obviously regulated dep. on power load - which is excellent, with head light same es before, max with 6k rpm 14,6 3. after 40 min stop-and-go run the battery voltage is 13,1.( 20 min after engine turned off) All in all an absolutely meaningful and supporting investment.
