Strange sounds

Hi guys

Since yesterday, I've been hearing this strange grinding/buzzing noise whenever I twist the throttle, but if I disengage the clutch the noise disappears.

It's not very loud, because at higher rpm the exhaust tone drowns it out.

Could this be bearing related?

Words of wisdom most welcome

Cheers

It's a 2011 with around 10000km
I checked today and it doesn't seem to be rpm related

Could it be vibration related? like something lose ?

Other than maybe a worn clutch bearing ? I don't have a lot of experience with bikes on a car this would be my diagnosis , a video or a .recording would help.

When it starts to make the noise, try putting a finger on the brake and clutch levers. Those can sometimes make noise when they vibrate.

My fuel cap sometimes has some vibrations. Press down on it too. Mine started around. 2,000 miles.

had the same problem with my bike.. ended up it is the new short levers that I have installed. The right side lever's "expandable" potion is a bit loose, which creates the buzzing sound.
My friend's case is cause his exhaust was fitted a bit loose, which causes the buzzing sound.

Levers, your key/keys, lights, cables, fairings, everything can buz from vibration of the engine lol, you can let it drive you crazy or just ignore it. Unless you think it is a mechanical malfunction then you might wanna try to pinpoint the noise.

My head light buzzes. I heard it a couple of times then I decided to find it. While riding, just start touching things with a firm pressure and see if the noise changes or goes away. I'm going to add in some rubber washers at the mounting points hopefully solves my problem.
