Highwayman might be on to something with the chain. On my 2017 650 I tightened up the chain after the 600 mile service
and it never had any gear whine at all. Then after - I noticed this oscillation sound at speed. Only at certain speeds and gears.
That was about 700 miles ago. I can still hear it but it's very faint now. Chain has a little more than 1 inch of slack.
Midway bottom run. It was about 2 inches prior. So OP it might be your chain is on the too tight side.
