I could feel something was loose when I tapped the bars with a hammer
I was surprised because it felt tight when I checked but when I took it out I discovered the thread lock.
The service schedule for the Inazuma has a list of bolts to check for tightness, amongst them are some of the engine mounts and exhaust bolts. The same for my other bike. Every so often I find one or two needing a tightening so if they have never been checked that would be a problem.
