FYI. In order to place the 2 metal plates you have to drill 4 holes in the plastic rack. The drill holes are indicated on the underside so it is easy and no errors can be made ….if done correctly…. The 3rd large metal plate is bolted on. See pictures.
Did those plates come with the factory bag? Do you have any pictures of the plates before the install? I am curious to see more of the bottom side of the plates that you need to drill into the plastic to mount.
It fits nicely on the tank. I secured it with the 4 straps/ribbons the bag comes with, rather than the magnets (for obvious reasons on this bike). To fill up the tank I loosen the two front ones to be able to lift the whole bag in a vertical position. It would be better if it was a clip system, as it would be easier to grab the bag on the fly when doing a quick stop, so I’m thinking about fitting some clips on the straps/ribbons. The bag transforms into a backpack which is convenient. There are plenty of other straps and clips on the bag, so maybe there is another way to secure it to the rack, but for now I’ve used te recommended”safest” option.
I’ll do some other pictures if someone is interested, as this one doesn’t show the bag much, but it’s the only one I have :
