thermistor-type warming element pad. This means its
resistance will change based on temperature.

FULL LENGTH HAND WARMERS
Full length hand warmers differ from standard length
warmers in that they are cut to match the bend of the
integrated handlebar hooks. Because of this, there are
separate warming elements for the left and right side of
the handlebar assembly.
To install, note the orientation of the hand warmer
element before removal. Reference the illustration and
notes below to properly install the element pads.
NOTICE
The left side of handlebar shown but the right side is
similar.
Assembly Notes:
• Install the heater element pads
q
.75 in (19 mm) from
end of the handlebars.
• Orientate the heater element pads 90° to the hook
bends.
