An old dirt bike trick was to fill the bars with silicone caulk. Never head of oil .

Or any heavy rubber hose that just fits inside the bar to quell vibrations before the Bar Snake came along.

It does have crash bars…I tried once to add dampeners between them and the frame but didn’t make any difference.

Gonna try the slip-on foam handgrip covers to see what that feels like.

Rest one hand on the crash bars when the handlebars vibrate.
In my case handlebars and crash bars vibrated in unison. I needed to remove the crash bars and adjust the mounting brackets so that the bars fitted perfectly. Mounting the crash bars under tension caused vibrations which repeated to the handlebars.

They did still vibrate a little, but after a few months and plenty of heat cycles I noticed they had disappeared.

Does your bike have crash bars or any other bolt-ons not listed above?
I had terrible vibes when I first fitted crash bars.

Go for a ride and touch everything you can reach while the bars are vibrating.
Does it vibrate at all rpm's?
