If the problem arose since the new tyres, it's worth checking they are on the rim true and properly balanced.
I had a very similar problem straight after I had new tyres fitted to my old Honda and they had not seated the front tyre properly.
Put it on the centre stand, prop up the front and spin the wheel. The tyre should run perfectly straight. Any wiggling from side to side, and that's likely the problem.
