Buzzing

This would be way too obvious, sorry, but does applying the brakes affect the noise? You could have debris trapped between the pads and the disc. Applying the brakes could make it sound worse or, sometimes, go away completely.

More likely, might be a wheel bearing. Does this "ring a bell?"

If none of the above, a true expert will likely be along shortly to help you sort it out.

update: I see now that @Frosty Rider posted seconds before me. That true expert may have come along sooner than later

That's not it.

That's not it.

It could sound different than that particular example. I'd take @warp9.9's advice and loosen the axle bolt and re-torque as he suggested.

Loosen the axle nut on each retorque to 30 ftlbs. And test ride her to see if it went away.

Warpo,
The Service Manual reports 48 foot pounds (65 Nm) front axle and 81 foot pounds (110 Nm) rear axle . . .
Just sayin' . . .

Does it start making the sound around 4k rpm in every gear?

1st, 2nd, 3rd yes. Not sure about upper gears

How many wheel bearings have you gone thru? Just looking for a change in his noise. If not he can put it back buddy

I should also mention this is a 2018 with 700 miles on it lol

It's probably your wallet after it just found out you bought a new rocket

 

[Jallen3.14]

You need louder pipes...

 

[Steel]

Does it do it sitting still at 4K, or just rolling?

Go right around the bike with a set of allen keys and tighten everything!! Check under the radiator shroud as these come loose on a new bike..lift the radiator side covers and tighten the bolts under there too...not sh**ing you m8...everything needs retightening. It could be a vibration of a loose cover somewhere. I did this on my new 16 Roadster and glad i did as found numerous loose bolts...Hope thats all it is.
