1. It may be easier to remove and install your seat if you first
remove the passenger backrest pad. To do so, open up your
trunk and remove the pad's mounting screws from inside. If
the backrest has a heater option, you must disconnect the
wiring harness plug. Replace the pad after your new seat has
been installed.
2. (See image to right) Pry out the two plastic caps in each of
the passenger grab handles, then remove both handles using
a 6mm Allen wrench. Watch for the four seat spacers that
could fall out; your new Road Sofa includes new seat spacer
replacements.
3. To remove it, lift the rear of the seat up while sliding it
towards the rear, allowing the tongue at the front of the seat
to disengage from its receiver under the tank cover. If the seat
has heater wires connected to it, you must unplug the wiring
harness from the seat before taking it off. (See Seat Heater
instructions if your Road Sofa has the optional seat heaters
installed).
4. Install the Saddlemen seat by reversing the above proce-
dure, sliding the front of the seat towards the tank cover as
you lower the rear. Make sure to use the four new round spac-
ers, and carefully insert the four bolts through the passenger
handles and into the threaded holes in the frame, being
careful to avoid cross-threading. Tighten the bolts and re-install the plastic caps into the grab rails.
5. The new seat may be slightly higher than your original seat which may have broken down and compacted over years of use. The new Saddlemen
will also lower with time but will not break down as the original seats often do. Take care when you ride the bike for the first time and until you be-
come familiar with the new “feel” and riding position.
OPTION: REMOVABLE BACKREST - ADJUSTMENT AND OPERATION
If your seat was ordered with the Driver’s Backrest option, there will be hardware inside the seat to receive the backrest bar (note that this will not
work with any fender-mounted backrest installation, or other aftermarket backrests). Access is through a slot (sometimes covered by a flap) on the
seat top behind the driver’s lumbar support. The metal backrest bar will get inserted into this sleeve and can then be adjusted both vertically or fore
and aft.
Your backrest may have come pre-assembled. If so, please skip ahead to #2.
1. ASSEMBLY Remove the loosely assembled bolt, washers and nut. Find the Backrest Bar and assemble it to the Backrest Pad by inserting the end
of the bar with the welded tubing into the chrome “C” bracket found underneath the pouch on the rear of the backrest. Re-install the bolt, washers
and nut. The fore/aft adjustment screw on the bar should be facing forward on the bike.
2. INSTALLATION Grasp the backrest bar and slide it into the hidden metal sleeve. You should feel it click into place. If the backrest bar is “floppy” or
loose after insertion, it is not inside the metal sleeve. Remove and reinstall, making sure it is firmly in the correct position.
3. ADJUST HEIGHT The height of the backrest is adjustable to two or three positions, determined by detents on the backrest bar. Adjust height by
firmly grasping the bar and lower or raise it to the desired height.
4. ADJUST FORE/AFT POSITION The fore/aft position of the backrest unit is adjusted by a thumb screw located under the backrest pad on the back-
rest bar. It is accessible through a hole in the backrest bar cover. Turning the screw in or out, will change the bar angle. This can slant the pad fore
or aft by three inches. The most common and suggested starting position is with the backrest aligned directly above, and at the same angle as, the
upward portion of the driver’s lumbar support. When you have adjusted the backrest to the desired angle, using a separate open end wrench, tighten
the included jam nut against the backrest bar to prevent the screw from backing out while riding.
5. ANGLE The backrest pad is designed to automatically conform to the angle of the driver’s back during riding. No adjustment is necessary.
6. REMOVAL Grasp the backrest bar. Pull it firmly up and away from the seat.
7. FOLDING The backrest can be folded forward by pushing the top of the backrest forward. This will assist passenger boarding.
8. TENSION The tension of the folding process and the angle adjustment can be changed as desired. Tighten or loosen the two horizontal bolts pass-
ing through the backrest bar at the hinge and backrest pad attachment points.
OPTION: WIRING FOR SEAT HEATER
There should be two wires coming out from the bottom of your new seat; one Ground (black) and one Positive (red). Connect the Positive wire to the
power source on your motorcycle. This can be directly to your battery's Positive (+) terminal, or spliced into a wire or connection that is powered only
when the motorcycle's ignition is turned on. Most motorcycles' owner's manuals have a wiring chart you can refer to. Connect the Ground wire to
your battery's Negative (-) terminal. Make sure that all connections are protected from shorting, and that any extra wire length is neatly wrapped and
does not interfere with the seat installation to the motorcycle. If you connect directly to the battery's two terminals, note that you must turn off the
Seat Heater switches whenever the motorcycle is parked.
