I recently fitted the Givi SR1161 rack and M7 top box plate, no pannier rails, to my ATAS and had a few minor issues during the process which might help others.
The product is great but my experience of working on the ATAS was nil.
The written instructions are pretty good but this GIVI video makes fitting it easier.
Note 1. After removing the rider’s seat I do suggest you put a towel or something over the whole exposed under-seat area before removing the bolts for the pillion seat. If you don’t and it slips out of your grasp it can disappear down into a 'well' beneath the rider’s seat and it is not easy to get the bolt out again.
Note 2. When removing the painted body panels either side of the seat watch for the strong clip hidden inside at the back end, see image 1. Try to pull this directly toward you and away from the bike with a gentle up down wriggle. Try not to twist the body panel too much because the inner plastic part of the panel to which the clip is mounted could easily break, see location of inner clip in image 1.
In the video they make it look easy to remove these panels but I suspect they are already lose before the camera shot is taken. Just be firm but gentle.
Note 3. At 10:46 in the video it demonstrates how to detach and lower the plastic clips holding the rear end off the back of the frame allowing you to fit the Givi parts into the frame tubing, see image 2. I cannot find this back end movement in the written Givi instructions but it is illustrated out of position. You won’t get the Givi bracket to fit the end of frame if you don’t follow how they lower it in the GIVI video. Note. You can get these clips to come off the back end of the frame quite easily even without the ‘Important’ note below.
There is no reference to this in the written instructions or in the video but it will make the reassembly task so much easier. Once you have removed all the panels and parts as per the video next locate a black metal body panel screw on the outside of both sides of the rear mudguard positioned two thirds of the way down toward the swinging arm pivot point. Removing these two screws allows sufficient rearward movement of the whole mudguard assembly so the large black plastic clips go back over the white bar on the tail of the frame when reassembly the bike, as in the video, see image 2 for clips. See image 5 for general location of these two screws once the panels have been removed. If you don’t removed these two lower mudguard screws there is a good chance you will waste an hour or two, possibly hurt yourself, break a few wooden tools and even curse a tad!
Once you have the back pulled down you can gain access to the open ends of the frame and fit the Givi Parts as per the instructions.
Note 4. Losing a Givi attachment down inside the frame.
The frame mounted bracket is held using a bolt and threaded wedge shaped to expand the channelled black tube inside the tail end of the frame, see image 3. This is good except, as in my case and before I got my screwdriver in place, the wedge can come lose during fitting and disappear way down inside the frame forever; Err…! To overcome this there is a small hole in the AT frame to the side and in the video it suggests putting a screw driver in there from the side to stop this happening, see blue arrow in image 4. I suggest stuffing something in the frame such a bit of sponge or bubble wrap before you even attempt to put these things in place. I also suggest lightly tapping the wedge into its housing so it is firm (but not so it expands so much it will not fit into the frame) before putting it into the frame at all. I got around my problem of the lost wedge by filing a larger nut with the same thread into the wedge shape. It did work but it is not ideal.
Note 5. Important! Repositioning the black clips over the tail of the frame.
To repeat myself, you will struggle to reposition the rear end unless you release the black metal body panel screw on the outside of both sides of the rear mudguard positioned two thirds of the way down toward the swinging arm pivot point. Once the rear end black clips are back in place over the white frame then replace the two mudguard screws and continue to reassemble the bike as per the video and or the Givi written instructions.
Because there are so many parts removed from the bike and in fear of losing bits I laid each part out on a large camping table along with the associated screws and fixings. I was pleased when I finished the job there were no parts left on the table that shouldn’t be there (Honda parts replaced with Givi parts) and that’s a first!
Other than these few points above the job went like a dream!
I hope this helps folk in the future.
