You have 17 kilometres on the odometer?

The bike is new?

If so better take it to dealer.

When did vibration start, it's an auto scooter yes can't be that much of a problem, maybe the drive belt.

With 17k on the clock, I would say it could be the engine pulleys lose on the shaft that would cause some vibration, unlikely to fall off, could just be a loose nut.

Get your local shop to have a look.

tires :  check the pressure !!!

 

else maybe you have new tires ,so you need to check the balance.

 

else check the wheel bearings

If the tyre pressure was wrong you would get more of a wobble than a vibration, motorbike tyers do not need balancing as they do on cars, but if the fitter did not get the tyre beads seated right on the rim that would cause a wobble.

Wheel bearings, unless the op has been climbing over mountains 17 k the bearings should be ok,  check by putting the bike on the main stand, hold the wheel at a 3 o clock position any movement can be felt by pushing the wheel back and forward ,also worn wheel bearings would make the bike wobble not vibrate .

Have you added anything to the bike such as a rack and box? (Not the human kind)

 

Is there an accompanying sound? (Not the human kind)

 

Would you describe the vibrations as a tank slapper? (Not the human kind)

i had a vbibration before the new tyre, i just added that info,  the drive belt is good think i need to take it to a PROPER shop they just put 60 lbs in my new rear tyre, not one of them own a pressure gauge, should be 33 lbs sq, and of cours i now realise i should not have posted this on thai visa, oh silly me, bye,

Oh, we forgot the obvious one. The GT is belt-driven, right? Check that the belt is at a correct tension, undamaged and correctly aligned with the sprockets (Is that the right word?).
