I have the original one, and i own a first series i don't know if we have the same fork.
Anyway, acerbis tank is plastic made very light. Probably two kilos, the original is metallic, probably 4 kilos and more.
Acerbis carry 9 liters more, but gasoline is lighter than water, so probably 8 kilos.
At the end,a full acerbis is 6 kilos havier

Don't worry ride your bike and have fun as much as you can
