handlebar shake with no hands on bars

[RaiderBill]

I have found that under 50-55mph if you take your hands off the bars the bars will start to shake and then get worse very fast. I did have a no speed drop 1 week after I bought the bike but now am coming up on 5k miles. Bike is smooth at any speed with hands on the bars. Yes I realize hands go on the bars but it should be smooth any speed hands or not. 70mph no hands bike is smooth. Front tire looks good with many miles left in it. Think when I get the back changed I will have them check the front. Watched some you tube videos with people jumping up and down on the forks after loosening things in the front and then retightening but I don't want to make things worse either. Any thoughts? I have a 2016 es.

Any thoughts?

Yeah, don't start new threads on the same subject you already have one for with lots of good advice.

Also, look through the many, Many, MANY previous threads by searching on terms like +handlebar + shake and other variations that become readily apparent after the first search. This is a nepRt subject.
