A hardcase system from Givi was mounted on the second GTS I bought. This
Monorack 2 is made from aluminium. However there are two carbon steel clamps
(in the front), but maybe those are homemade by the former owner or shop. Also
the allen screws are carbon steel.
See the right picture for the lefthanded mountingpoints (captured in the green foam-line).
Left picture shows the left mountingpoints. The redcolored tube is part of the
Scottoiler chain lube system. The big black plastic part in the left upper
corner is the mounting point for the original left Krausser hard bag. In the
right upper corner you see the back of the left turn signal bulb holder.
The carbon steel mounting clamps on both sides of the bike, are attached by one
of the bolts that is used for the original hard sidebags.
On the right picture you see the righthanded rack mounting points (captured in the green foam-line on the bigger photo). Also visible the kind of T shaped frame part from the hitch
construction. The resevoir with the blue and red nuts, is holding the nitrogen
for the custom made Technoflex rear shockabsorber.
In the plastic rear part, under the seat, where a lot of electric compenents
are attached, there are 4 holes needed for the mounting clamps to come through.
Pictures of the holes in the plastic rear part from both sides. Could be make with a drill and file. But the plastic also will melt with a heated screwdriver or something like that.
The plate where the hard bag is clicked on, is adjustable in a more or less horizontal position. You can see the adjusters with marks and the round nut in the left arm. The two round nuts and the two allen screws are holding the plate and arms together. I guess it would be better if there was a bigger plate in a way that the allen screws could be placed more to the outsides. Now the arms do touch the plastic sidecovers sometimes when they moved by vibration.
Here it is with the topcase attached. The arms are hiding a little part of the turnsignals lenses. I don't know if you get trouble with that in certain count(r)ies, may be some extra LED turnsignals placed on the arms will compensate it. In my case only the left turnsignal is used. For the right corners the turnsignal on the sidecar is used.
