Front Disc brake noise

Once a rotation i can here the pads and disc scrapping together. Any ideas of what this is?

If it is a light swishing sound, it is normal.

Check your tire pressure... I swear Honda unintentionally engineered the rotors to howl at a certain pressure. Mine starts to howl around 30psi.

if you love your motorcycle, set it free.. if it comes back and hits you.. you highsided

Normal. This is my second bike that has made that sound. I kept checking for excessive wear and overheating the first time I heard it. Nothing. Had a mechanic check it out too. Normal.

sounds normal. What about when your front brakes squeak when going really slow. Like when your about to stop. my front brakes squeak. My '06 919 only has 800 miles on it. I probably should just take them apart, relube and sand the pad a bit right?

front brake rubbing is pretty normal. Mine does it. Used to have the famous 919 squeal when coming to a stop as well, but that kinda just went away.

dunno what you guys are talkin bout... i have the normal disk break swoosh every bike diskbreak has.... but no squeals or howling... and i run at all different tire pressures (which should have Z E R O effect on the disk breaks)

at 11.5k miles and never had any issues with noise at all. Im using OEM pads, and rotors, i do not use any type of noise reducing paste on the back of the pads at all. I DO however take the pin out on the front pads every now n then to clean it up from corrosion, as well as where the pad sits in the caliper to make sure the pads can move freely.

Ya this sounds a little strage to me. I have had other bikes with the same type of brakes like a cbr600. It sounds to me as if the front brake disc has a high spot, and it hits it ever time the tire rotates 360 degrees. like i said the disc seems ok, but i guess the only way to really know is to check it w/ a micrometer.
