VRRPM series regulator/rectifier units for bikes
with permanent magnet alternators.
Don't know what your bike has? eMail me or see our FAQ page.
This regulator/rectifier unit is for bikes with 2 AC leads and early Honda singles
and twins with a split charging coil (see article 4 on our FAQ page.) Max charging
is set at 14.5v.
It measures 65 x 95 x 38mm thick. The mounting holes are 80mm center to center
and it may require some custom mounting on your bike. It comes equipped with
11" leads and the hardware and connectors shown in the pic below.
All Honda singles and twins up through 1978, Kawasaki KZ400, KZ650, KZ750
twins, H2 triple, KH triples (but not all years, ask if you're not sure)
Suzuki T and GT two stroke twins and many others.
It can be used on all 1970s and older BSA, Triumph, Norton and other British bikes
with a 2 wire stator if converted to negative ground.
Ask if you're not sure it will work on your bike.
The VRRPM2 series regulator / rectifiers are designed to be a very heavy duty unit for any bike that
they are sold for. The pictures above were taken side-by-side with a OEM unit off a KZ650
This unit is for mid years models of the KZ650 four and late model KZ400, KZ440 and KZ750 twins.
For bikes with alternators and with 3 AC leads.
There will be models for at least the following bikes. Most Yamaha, Kawasaki and Suzuki fours through the 1980s.
There are too many models to list them all now.
This unit ships as you see it with about 10" leads and the
connectors installed to so that it will plug right into your
This one is for 1969 to 1977 and older Honda singles and
twins. See FAQ articles 4 and 5 before purchasing. It is
configured so that it plugs right into the old rectifier plug. The
old regulator is then removed and left off.
On pre1975 bikes the yellow and white wires will have to be connected
together (they are from the factory on late 1974 on.)
It comes with a 4 prong female plug installed. Since this unit is
much larger than the OEM rectifier, custom mounting is required.
The VRRPM2 is for all permanent magnet alternators equipped bikes that have 2 AC leads from the stator.
This unit is only for bikes with 12v electrical systems.
This unit is specifically For the GL1100 and GL1200. It's a
direct replacement that plugs right in and bolts up like the
The VRRPM series rectifier / voltage regulators are made for us by another manufacturer
to our specs. While these units are very well made and designed to our philosophy, we
cannot cover them with the lifetime warranty. All of the VRRPM series units will carry a
no BS 2 year replacement warranty.
Connector plugs will be installed on request and are included
in the price of the unit...
This unit will is for bikes with 3 AC leads from the stator
Max charging is set at 14.5v. This unit measures 65 x 95 x 38mm thick with 11"
leads. The mounting holes are 80mm center to center and it may require some
custom mounting on your bike.
This unit is great for bikes like the GS series Suzukis and Z and KZ series
Kawasakis that have a 3 wire stator, Yamaha Maxim, Seca and Viragos up to
1100cc and many others.
Introducing our VRRPM3S, a smaller version of the
This unit is for bikes with 3 AC leads from the stator. We managed to get
the same regulator as with a larger unit about into a smaller package by
pairing it with a slightly smaller rectifier. Because of this, we only
recommend this for bikes up to 650cc.
Max charging is set at 14.5v. This unit measures 45 x 70 x 30 mm thick
with 11" leads (about 24cm.) The mounting holes are slotted to fit on more
bikes with less custom mounting.
This unit is great for bikes like the GS400, GS450, GS550, GS650, KZ550,
and many others.
This unit is for the GL1000 Goldwing. This heavy duty unit is
almost plug and play part for the GL1000.
A one wire modification to the wiring on GL1000 is required to use
this part after the OEM regulator and rectifier is removed.
This unit is an improvement over the earlier separate voltage
regulator and rectifier that Honda installed on these bikes.
This is the same unit as above but comes with instructions and a
wiring kit for the GL1000.
This is a picture of one I installed on my GL1000. As you can see it mounts
right up and connects to the original rectifier plug. All you have to do is install
the one wire privided with the unit and you're good to go...
Not pictured but the same as the VRRPM2-HCB above but with a male plug for the
SL350 and 200cc and smaller Honda twins.
Note: the late production KZ650's
use our VRRPM3 or VRRPM3s.
Although this is the Highest rated unit we carry, it also works great on bikes with low output alternators. I recommend
it for bikes like the S1~S3 Kawasaki, Chinese 250cc Scooters, Bridgstone twins and the small Yamaha Virago twins. It
also works great on the Hyosung GV650.
I will need notification of what bike you're going to put it on and I will hold shipping until I have this info so I can be sure
and have it set up for your bike.
