The extra gear weight sounds evenly distributed, and pretty insignificant in the big picture.
I would however consider the passenger's weight, whatever it may be, and if the subframe can handle it.
I would have the suspension resprung and valved for the weight too, otherwise, the handling will be poor.
I would also upgrade the front pads, I'm still sold on EBC "Extreme Pro" carbon ceramic, as they Do stop you sooner.
As
@Bumblebee mentioned above, tire pressure is Very important also.
And, for what it's worth, 20ish years ago I was with a group on my 94 zx7, a couple showed up that I never saw before or since, on a blue 2000 Busa...and they Each had to be pushing 500 lbs!
I've never seen so much ass on a motorcycle, even to this day!
How long it lasted or held up I'll never know, but, the group nailed it on the highway, and the newish R1's and the zx9's walked away...right along with the Busa...that they couldn't leave...and my 750 had no chance of catching...with a half a ton of ass on it! lmao!
So yeah, they can take the weight.
Should you? Probably not.
