Bike won't start!!

[His Dudeness]

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?

Good point. There could be something draining the battery. After you charge it try starting it. If it starts great the battery was flat. With the ignition off take one of the wires off the battery and connect a mulitmeter between the wire you took off and to the battery post. Check if there's any current flow when the key is off. Or if you don't have a multimeter do the same but connect a bulb between the wire and the battery post. If the bulb lights it shows current is flowing and there's something draining the battery.
