Hum noise like an owl

[triplez]

I have a weird hum noise that sounds like an owl. Like a "hooo" no constant rpm or speed or gear.

Is this normal? I also own a speed triple and it makes a million noises so I'm not overly worried. Just curious if anyone knows what's making the noise. Possibly air duct?

Yeah i have the same wierd noise, but dont really notice it now but i did when it was new as i think we tend to listen for any noises during running in .
I think its coming from the front end low down somwhere but with mybike its only seems to be between 50 to 60 kmh

Yeah. I think when the engineers build a bike they don't put a lot of time into noises

My guess is that you're hearing the intake noise. The inlet for the airbox is on the bottom side of the airbox near the steering head. It may seem to be coming from the front end...
