Honda say 10kg but hey-ho wtf do they know about designing, producing and selling ptw's.
Honda knows how to design good scooters and such but they also know how to avoid civil liability. I think those ridiculously low weight limits (on my Kawasaki rack: 3 kg) are there in case somebody would like to sue them for damage and injury if they endorsed cargos that could theoretically be close to or might even surpass the bike's capabilities given the right combination of misluck and stupidity. In reality, they can take much more than just a few kilos.
Here in Thailand, an ordinary workhorse like the Wave motorcycle (underbone) can perfectly well accommodate three people or more. I've seen a whole family of three children, husband and wife to mount a single Honda Wave and get away with it no helmets on. The PCX has this abominable hump that I think was partially designed to NOT facilitate mounting more than one passenger comfortably.
That said, it is true that a vehicle behaves differently under load. My Kawasaki W650 would start to wobble if I went beyond a certain speed with the side trunks attached. Without them, it was much more stable.
