Joe, from my conversation(s) with Yamaha after my subframe broke they told me with using the Yamaha heavy aluminum rack (the one I have and the only one you have to cut out things I think) the givi sr 357 or Shad tube rack that they (Yamaha) only recommend a maximum of 10lbs over the weight of the top box, 10lbs !
That all said when my subframe broke I weighed my Shad 50l topbox which weighed in at 15lbs empty, the equivalent oe Yamaha box was 25lbs and the Yamaha rep got quite testy when I asked him about the additional 10lbs of the Yamaha box, I don’t know what the Givi topbox weighs.
I will also add that the rack you have supplies zero support and actually adds stress to the very poor rear subframe, that’s why I always recommend the heavy aluminum Yamaha rack, the Givi sr357 or the similar Shad tube rack as they all provide support to minimize any flex in the rear subframe. I also personally like to add a stiffy kit to keep the back of the bike together if the subframe does break which it did for me when mine broke. Although the stiffy by itself will not prevent a broken subframe as it provides no relief from the subframe tab’s flexing.
If you look in the owners manual it recommends a max of 7lbs as does the sticker on the subframe under the seat. I was very conscientious of no more than 5lbs in my 15lb Shad topbox for a total of 20lbs, I originally used a Shad “X” type steel mount that mounted exactly the same way as your rack along with an installed Stiffy and usually carried nothing in my topbox using it mostly for storing things at stops only with a very occasional trip and no more than 5lbsin the box.
Imho, I wouldn’t carry anything on that rack, not that it’s a bad piece but just because the subframe is so poor, they are about $600 for a new one with you doing the labor to change it out. My .02
