Brake vibrations

[Xemein]

Hi everybody: This is my first entering in your board and I would like to express my sorry due my poor english...because I am Spanish.
Well I will try to explain my question. Every time I have to use the front brakes driving top to 120 kmp a poor vibration appears from the front wheel. It dessapear a few seconds after but it is not very glad for riding. I have make messaurement from the runout of the disc and it is like a few out of specification (limit 0,3 mmm and I have 0,6mm only the left one) What is the matter?
Thank You.

Could be that your rotor is warpped.

Sounds like a warped rotor to me. If the vibration is bad then gets better though... I am still guessing warped rotor.

Do not worry about it,Brakes are poop on the front of the busas, just bring a parachute with you,back brake will just lock up and leave you weaving all over the place,trick is to try control that weaving,easier done than said.
I have 2 busas,and none of them like to stop,they love being rode hard,so to stop I just have to always have an escape route planned.
Great bike for getting the blood flowing.
