I was warned online in one of my threads, by another Stromtrooper that this was an issue. I have since orderd the correct full thread m8x60 from Amazon. Since my EVO racks are still on back order for the next week, I should have these screws in before I receive the racks. As an aside, I just ordered my left Motech Trax ADV side case. Ordering the right side in a couple weeks. This is in effort to keep the Wife-Unit happy
I got the correct (60mm full thread) screws yesterday but didn't have a lot of time to mess with the bike. I did notice, however, that the rear crossbar that mounts to the tail fender doesn't have holes in it to match the two holes that the U.S. license plate bracket uses. A pair of 1/4" x (I think it was) 1.5" stainless screws solved that problem for me. I drilled the two holes into the plastic fender per the instructions and then used the longer screws to go through the license plate bracket then through the SW-Motech crossbar and through the newly drilled holes in the fender. This seems to work fine.
However, test fitting the racks or at least attempting to, reveals yet another issue. The U.S. license plate bracket (which I assume is the same across the U.S.) has two red reflectors mounted on its sides. The bracket and the reflectors are in the way of the mounting holes for the side carrier's quick-disconnects on that crossbar. I removed the reflectors (they're not a legal requirement in my state, but they are in some others I believe) and bent the bracket so that the ends, which are normally at 90 degrees from the rest of the bracket, were far enough out of the way. I may go back and cut those ends off and find or fabricate an alternate way to mount those reflectors. I'm thinking a simple bracket attached via the two bottom holes on the license plate.
I did get the racks test fit and in spite of these issues I'm pretty happy with them. Unlike what others have said, they are not wide / far out from the bike at all. That was true on the older V-Stroms due to the high mounted exhaust but is not the case here.
Finally, I also noticed that I did not have to push the exhaust can down in order to fit the Trax ADV cases. I'm wondering if anyone else did or did not have to relocate / lower the exhaust can either on a '17-'18 model or a '14-'16 model. There's not a ton of space but there is some space there, at least 1.5" - 2" maybe more. Again, I didn't have enough time to mess with it as much as I wanted to. There may be reasons to move it anyway, such as heat, but I'm not sure.
I will post up some pictures later in case they're helpful to anyone.
