how much does my vf1000fe 1984 weigh ?

here is the label on the frame ,is this really correct, seems a lot 438kg, A MotoGP repsol Honda is 137Kg
need a super heavy duty bike bench so it can handle at least a TON

Kerb weight 258kg,the figure quoted is maximum weight fully loaded.
Kind of rules out you me and all the camping gear going on your bike
