The low-speed hands-off nuisance shake is due to the front tire. Replacing it with some other type/brand of tire will solve this problem.
Headshake at constant higher speed in a straight line on smooth pavement should not occur, and is an indication that something is wrong. My experience has been that improper wheel balance usually starts making itself felt around 110 - 130 km/h and gets progressively worse from there up. Out-of-round or unevenly worn tires will also cause this. Loose steering head bearings won't help. Has your bike had the front-wheel replacement recall done?
Headshake over bumpy pavement while accelerating can be improved about 90% by softening front preload. Get it so that front sag (with you aboard) is in the 35 mm range for street riding. This will probably require backing the front preload adjuster almost all the way out (more or less depending on your weight).
A steering damper is highly recommended, but it's not a substitute for having the suspension settings right, and it's not a substitute for fixing something else that's wrong with the bike.
Helibars, MRA screen, Ohlins damper, reversed shift pattern, sorted suspension, braided lines, Michelin Pilot Power, all else stock 'coz it's fast enough!
