FOR PROPER INSTALLATION &
SAFE OPERATION, PLEASE
READ ALL INSTRUCTIONS
BEFORE STARTING
Unpack the BackRest Assembly and parts
bag from the shipping container. For the
R1100/R1150GS you should have the
following items:
2 - M5 x 12 button head cap screws
2 - M6 x 40 socket head cap screws
2 - M6 x 25 socket head cap screws
2 - M6 nylon locknuts
2 - #10 flat washers (small)
4 - #12 flat washers (large)
2 - 6mm split ring lock washers
1 - Front (long) subframe bar
4 - Rubber grommets
1 - 5 mm hex wrench
Remove the two large ring-pins holding the
BackRest in the folded position by gently
pulling on the rings. These ring-pins have a
detent ball and will “click” as they clear each
hole.
Unfold the BestRest. As you do this the Slide
Assemblies in the middle of the BackPlate
will drop down. Align the 5/16” holes at the
ends of the Lower Slide with the holes in the
two upright Rear Posts. Reinsert one of the
5/16” ring-pins thru these four holes to secure
the BackPlate the upright position. Store the
remaining ring-pin in one of the two
remaining storage holes. As you move the
BackPlate thru its full range of motion you
may need to remove the second ring-pin and
relocate it to another storage hole.
See page 3 for information on how to
configure, adjust, and secure your BackRest.
BackRest In Rider’s Position
(Only for R11xxGS)
1. Remove passenger seat and toolkit lid.
Remove the 6mm screw holding the rear of
toolbox. (Fig. 1)
Fig. 1
2. Rotate rear of toolbox upward, then pull
gently rearward (Fig. 2). The front of the
toolbox is held in place by two plastic tabs
that fit into the forward cross frame member.
Fig.2
3. Installation of the Subframe Bar. To hold
the BackRest Assembly onto the motorcycle,
you must install a Subframe Bar (Fig. 3). It
will fasten beneath the cross frame rail, which
is located just in front of recess for the
toolbox. (Fig. 3 shows Subframe Bar next to
the cross frame rail.) Two M5x12 pan head
screws hold this Bar tightly against the
underside of the rail, preventing the Bar from
shifting. The larger 6mm holes are for the
screws that hold the BackRest in place. All
four screws will pass thru the two small slots
in the frame as shown in Fig. 3.
Fig. 3
Special note: The Subframe Bars shown in
these photos are prototypes without the
pressed screw fittings.
Special note: The Subframe Bar is marked
“UP” on one side. Make sure that the Bar is
mounted properly or the pressed screw
fittings may come loose.
The fittings should
be on the bottom of the bar.
4. To assist placing the Subframe Bar under
the cross rail, we suggest using a small nylon
ziptie or piece of string. Insert the tie thru the
hole in the Bar and thread the end of the tie
up thru the small slot in the frame (Fig. 4a).
Pull the Subframe bar into place (Fig. 4b).
It’s much easier this way!
Fig. 4a
Fig.4b
5. Once the Subframe Bar is in place
beneath the frame, LOOSELY thread the two
M5x12 flat head screws (with flat washers)
into the Bar (Fig. 5a).
We recommend use of a semi-permanent
thread-locking compound to hold these 5mm
screws. “Blue Thread Lock” will prevent the
screws from coming loose, which would
cause the Subframe Bar to drop or otherwise
move out of alignment. Do NOT use a
permanent (red) thread compound.
Fig. 5a
The two (empty) M6 screw holes must be
equidistant left and right. They must also be
centered fore and aft in the slots (Figs. 5b –
5c). If they’re offset in any axis, adjust the
Subframe Bar as needed. It’s important to
align the bar properly or you’ll have difficulty
inserting and threading the BackRest hold
down screws.
