Weight limit is a funny concept. I remember Columbus had a weight limit on the SL tube set that for most of my riding life I was above that. Then I would see a young man the weighed all of 150 lbs. wet and he would trash the rims and bend the axle. I put it down to how you ride. The example I always do in my shop is jump up and land soft and you would feel nothing then I would jump the same but let my legs remand rigid and boom you would feel it run though the building. It is a combination of the two yes if you are 230 lbs. you will at sometime bend or brake an axle and if you weigh less it will not happen as often I mean it is simple math. I have riders here that tip the scale at 260 and ride with no problems but I rebuild the wheels and replace the axle more often as preventive maintenance.
