All of my VRR4-H series regulator / rectifier units are the same other than the length of wire and plugs that connect
them to the bike's wiring harness but the are otherwise exactly the same.

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 do not
use a minimal or custom wiring harness. For bikes that still use the
original wiring harness, see the VRREM7-H 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.

The 550 Nighthawk has a well known
problem with stator/ field coil assembly. I
highly recommend testing the stator and
field coil or installing the updated stator unit
from Honda before ordering one of my
VRREM4 units.

Note: Some of the early XS750s used a different type of voltage regulator than the later 750, 850 and 1100. The
later bikes had full power from the brown wire to the field coil and the green wire from the field goes to the
regulator. On these the regulator would ground the green wire as needed to complete the circuit. The earlier bikes
had one wire from the field grounded and would get positive from the regulator to complete the circuit. To use this
unit on the earlier bikes you will need to modify the wiring on your bike to match that on the later bikes. It is a one
wire change and you can eMail me for help with this.

Like with all Oregon Motorcycle Parts regulator/rectifier units, full charging is reached by 1200RPM. We feel
that much of the problem with OEM regulator/rectifier units is that they are made too small and the heat from the
rectifier is dumped into the voltage regulator and slowly cooking it. Leaving an airspace between the rectifier and
voltage regulator is part of our design philosophy.
We have been unable to obtain the OEM plugs Honda uses to connect the regulator/rectifier unit. Our
VRR6ST11 unit comes with a connector harness with 6" of wire and the necessary supplies to splice it to the
wiring harness on your ST1100.

The easy way to tell if your bike is an early model is if there are 3
yellow wires from the stator.
The later series KZ had 2 yellow wiresf rom the stator. See the
VRRPM2-KZc for these bikes.
