A little headshake when decelerating from 50 mph to 40 mph is very common. Was happening when I worked in the industry in the 70's still happening today.
Every motorcycle forum I have ever seen has threads questioning this. There is even an explanation for it having to do with rake and trail and weight transfer, tire age, wear, inflation, steering head bearing tension, front wheel bearing condition and other things, but I can't recall all the specifics. Best general advice is check tire pressure and condition.... and don't let go of the bars.
