I agree with checking the bearings and u-joint. I would also replace the back tire since you have some cupping.Pull the clutch and see if the vibration continues.
The typical places to look: tires, wheel bearings, steering bearings, u-joint, swingarm, etc.
If you have a Lift that the rear drops down to suspend the rear tire (or someway a raising the rear end safely), you could start the motorcycle, put it in gear to get it up to the speed where you hear the or fill the vibration. Then you will know if u-join is causing the problem.
