As WIDEOPN-X3 has said, Welcome to the world of two wheels, life as you know it is about to change.
Reading your posts it seems like you would go off-road so dismiss all the naked bikes as they are not meant for anything but road, adventure bikes are what you are after, all the bikes you mentioned(Mt-07, Z1000 and especially the superduke) will not do off-road with their street tires and suspensions.
With your budget you will be able to pick up a nice f800 BMW or even an older R1200 GS, Truimpth Tiger or if you lucky a KTM 1050 or 1190.
Now just back to the fact that you have not ridden before, get some training in any way shape or form, any bike can kill you if you so don't think you are out of the woods on a smaller bike, things happen in the blink of an eye so be careful out there.
