I've had a loud fast buzzing noise from the battery area before and it was a knackered battery. Not enough volts to turn the starter. You could check this by jumping the bike from another bike or a car. Or borrow a mates battery and see if that gets it running.
As you say, it's a new battery, do you trust the supplier? What about another drain somewhere? got some aftermarket electrics on there that could be running it flat?
