Cruising along, braking, accelerating, turning, carrying luggage, both hands on the bars...?

Way more info required.

Usual suspects are oddly warn tyres or knackered/loose headstock bearings.

Check your tyre pressures as a starting point.

Check the wheel rim for missing balance weights too.

I would check tyre pressures, check wheel bearings and check balance before delving any deeper.

Also have a good look around the tyres for any damage or unusual wear,

one of the hamsters running round in your front wheel is getting a bit old and has to stop periodically, making the wheel unbalanced.

Is the tyre coming to the end of its life? Vibration is one of the bugbears of a tyre just prior to it reaching it's minimum tread.

Put it on the center stand, put something heavy on the back seat so the front wheel is free to spin.

Check the tyre still has good tread, is correct pressure and has no bulges/defects.

Check the wheel spins freely/no hard dragging and that you still have material left on your brake pads.

Check if there is any lateral play in the wheel, as in keep the forks straight and see if the wheel wiggles at all from side to side (it should not)
