Voltage Regulator/ Rectifier Units
For bikes with electromagnet alternators
Since COVID and the economic turndown, I've been working on my own here and I've had to make all the parts on this page special order items. Most of the time I will have to make these units to order but I try to keep a few on hand. Send me an eMail and let me know what you need and if you can wait for it...

About OMP
All of our VRR4EMH series regulator / rectifier units are the same other than the length of wire, plugs and what ships with them.

1100cc Honda fours
$174.00
VRREM4H1
Regulator/Rectifier unit for the
SOHC Honda CB650 four.

VRREM4H2
The VRREM4-SOHC for 1969~1978 SOHC Honda fours.
This unit comes with the connectors and mounting hardware to install it on your bike. This is the easiest options for full on custom bikes that use a minimal or custom wiring harness. There are 5 wires that connect to the alternator side of the engine leaving only 3 to connect to the harness.
For bikes that still use the original wiring harness, see the VRREM7H lower on this page.
This unit comes with 2 repair harnesses to splice it into the wiring on your bike and a packet of splicing supplies. All the terminals to populate the plugs for the harness in case you don't need the extra length of the harness sections. Also included are 6' each of 14 gage primary wire for the back bone wiring of the bike (red with a white stripe for + and dark green for ground.)

VRREM7YRD for Yamaha 2-stroke twins DS7, R5, RD250 and RD350.
Because of customer demand this unit now comes with micro plugs like Yamaha used on the original regulator and rectifier.

The leads are the same length as the original regulator and rectifier leads and the unit fits nicely into the place where the original regulator mounted.
