A bit random here, but anyone knows if other bikes make this kind of noise?

I just realized my bike makes some kind of whining noise only on 5th gear around 5k-6k rpm.
I've asked owner groups and workshop but no answers.

I have a video below showing when it does the weird noise, but you might need to wear headphone to hear it.
Around 1:20 you can clearly hear the sound but I've also put subtitle when the *weird noise* happens.

If anyone knows if its normal or a symptom to a problem please tell me.
Kinda worried here

so I compared with these 2 vid and I can also here the same noise in some part.
I guess its part of the engine sound then

just a casual question, you don't gear up at all?

belum pandai kot
or mau power all the time hence tak up the gear to 6 to cruise
