Here's a quick step-by-step on how to swap from the dual seat kit to the single seat kit.
Do not hesitate to suggest improvements in wordings. Thanks!
Difficulty: Easy
Time to complete swap: +/- 1 hour 30 minutes the first time you do it. 30 to 40 minutes once you get the hang of it.

Step 1:
Remove top screw on top of the seat-lock barrel to free the seat-latch. This latch is not the same than the one for the single seat kit. Make sure you have a longer latch in your kit which is not covered with a plastic tip.

Remove the nut holding the locking barrel and pop it out of the dual seat.

Step 2:
Remove the left and right seat brackets. These brackets are screwed on the fuel tank, they are not needed for the single seat kit.

Step 3:
Remove left and right panels covering the silencers. The holding screws are situated on top. Easy stuff...

Step 4:
Remove the 3 holding screws of the pillion foot pegs with an Allen key.

Step 5:
Remove left and right silencers. While it looks intimidating, it is extremely easy on the Super Duke. (On the 990 Adventure and 990 SM it's quite tricky).
You need to remove the silencers to free the underseat 'bucket' because the silencers are just too large.
You first need to loosen the exhaust collars if you have a pair of after-market pipes. These are FMF Apex, very easy to work on and surprisingly extremely light!

Now remove the silencer holding screw bolted on the subframe.

Slide the silencer out of its guide while gently doing some rocking motions to free the silencer off the intake exhaust.

Step 6:
Remove the top screw holding the underseat compartment.

Step 7:
Remove all the screws that hold the wirings.


Unplug the rear brake wires and indicators.

Step 8:
Remove the underseat compartment of the Dual Seat kit.
This is for me the most frustrating step, because you have to be careful of all the wires which go between the underseat compartment and the fuel tank. the rear comes out by bending it out slightly under the subframe. Now you should see why the silencers needed to be removed.

Step 9:
Now place the underseat compartment for the Single Seat kit. Same story than the previous step but in reverse order. Again, this is for me the most frustrating parts because you have to be careful of the wire system. Make sure no wires hang unnecessarily below the compartment.

Step 10:
Place the single seat front support bracket. This part only needs to be installed for the single seat kit.


Step 11:
The part below fits at the rear of the subframe. It holds the rear fairing locking system of the single seat kit together.
Slide the long part, which has 2 screw threads on each sides, in its cylinder. And fit both parts through the subframe and underseat compartment.
Check how both parts fit on the photo below.

Step 12:
Place 2 large headed screws, one at the bottom of the underseat compartment and one to hold the rear faring locking system.

Please note that the release mechanism of the rear fairing needs to be placed on the left side of the sub-compartment.
Step 13:
Place the silencers using Step 5 in reverse. It should not be difficult, watch out for the holding brackets securing the silencers in the middle part, it is a bit tricky but not really difficult to place the silencers back.
Step 14:
Place the rear fairing support screws where indicated on the subframe. You need to place that special washer in the screw as shown below.


Step 15:
Now take the top screw which fits on the locking barrel in 'Step1 ' and the locking barrel. Screw the dedicated seat latch for the single seat kit. It is longer than the dual seat kit locking latch and is not covered with a plastic tip.

Connect the rear light and indicators wires and lock the rear fairing in place.
Step 16:
Using your key, fit the single seat and lock it in place. If the seat is not secured and comes out, it means you placed the locking system latch up-side down.

That's it!
