My goodness, no.
The subframe of my Zongshen 200GY-2 is
very strong. I'm confident the subframe of the Zongshen RX3 is very strong as well. All Chinese luggage racks are
also very strong.
I installed a very strong luggage rack on my Honda XR650L.
The subframe of my Honda XR650L is not noted for its strength, so I reinforced it.
The Garage Pro Travel Trunk and its mounting plate are very strong.
Needless to say, one should still exercise discretion, and not overload a travel trunk. When heavily loading a motorcycle, one should also take care to keep the weight distributed, and as low a possible.
