Headshake as this thread is calling is very common on a lot of bikes crossing all brands weight and size bikes, can be made to happen by knocking the end of the bar while hands are off in decel. Some will be worse some more speed critical and some not at all or until an exact condition occurs.
Many causes and variables- tires, load and weight distribution, head bearing tension, swing arm bearing tension to mention a few. Tires and tire wear seem to have the most effect.
That being said handsoff decel shake primary cause is "HANDS OFF"....arms and hands are part of the total steering damping system and like others stated earlier if you keep your hands on the bars you will never find the shake and it is pretty much normal.
