MOUNT PROXIMITY SWITCH
This manual covers the installation of the Rev II Speed sensor bracket for Harley Cush Drive
Models. Start by removing the existing bracket, and peeling the sensor off the old mount. You
may wish to cut the wire ties that hold the sensor wire so you have more leeway for the new
bracket.
This step is crucial!! Understand it before starting. The proximity sensor tells the system
how fast the bike is traveling. The proximity sensor mounts to the swing-arm at the rear rotor.
You need to jack up the rear wheel so we can spin it to test the sensor and its placement. Make
sure the bike is in neutral.
Remove the bottom bolt from the
right shock at the rear of the bike.
Insert the top of the bracket
shown at left, behind the shock
and in front of the hole in the
swing-arm, so the bolt will pass
though it when reinserted.
NOTE: the yellow sensor seen
here will be close to the brake
rotor and below the shock bolt
(see below).
Reinsert the shock bolt and
tighten the nut, while holding
the bracket forward against
the swingarm as seen here.
Get the shock bolt snug!
We next have to set the
sensor so it finds the spokes
of the brake rotor (not the
bolts as in the past!) at a
distance of 5MM (about ¼”).
Be prepared to bend the
bracket to get to the sensor in
the correct position.

When you think you
have it, turn the ignition
to Accessory position,
and roll the wheel to
make the spokes of the
rotor pass by the sensor.
Each time one passes
the sensor, the LED on
the sensor should go
bright then off.
If this is not happening,
you may need to get the
sensor a bit closer to the
brake rotor (5MM is a
very small distance!). If
you have to move the
sensor closer, you may have to bend the bracket just a tad (you may even need to loosen or
remove it to bend it as you need to). No matter what you need to do, you MUST make sure that
as the wheel turns, the light works as described above! Once you are certain, tighten the shock
bolt and test it again! Rotate the wheel past all 5 spokes on the brake rotor and make sure the
light blinks and goes out each time. If all is perfect, you are done! The automatic retraction of
the legs as well as their deployment RELIES on this sensor being placed perfectly! Now we can
route the wire.
Reroute the wire on the top of the swingarm as seen here using wire ties. As in the initial
installation, make sure there is enough slack to allow the swingarm to pivot!
Test your new install by driving the bike with the system on and the legs up. Watch as the
yellow light goes on and off. This should occur at approximately 6mph. No need to lower the
legs for this test. Just make sure the light turns on and off as it should!
