Moturo voltage regulator rectifier compatible with Honda CB 750 K1-K8 F1 F2

Moturo Voltage Regulator Rectifier for Honda CB 750 K1-K8/F1/F2

The Moturo voltage regulator rectifier for the Honda CB 750 K1-K8/F1/F2 (model years 71-78) converts the alternator's AC voltage into stable 12-volt DC voltage and charges the battery. Original design, ready for installation.

The regulator is located on the frame under the seat and rectifies the AC voltage from the alternator into 12-volt DC voltage. The voltage remains within the tolerance range, ensuring the battery is charged and that light bulbs in the electrical system do not burn out. The connections and plug configuration follow the factory specifications for the Honda CB 750 K and F models from 1971 to 1978.

Replacement takes about an hour using a socket set, screwdriver, and a multimeter for voltage checking.

Frequently Asked Questions

Does the regulator also fit the CB 750 from 1979 onwards?
No, it has a different alternator and plug configuration. Suitable for CB 750 K and F models from 1971 to 1978.

Do I need a TÜV registration?
No. Original replacement part design; no separate registration required.

How do I check if my old regulator is defective?
Use a multimeter to measure the vehicle voltage with the engine running — it should be between 13.8 and 14.8 volts. Values above or below this indicate a defective regulator.
