I have a 97 zx6 ninja and whenever I apply my front brakes i get a rythmic shudder. I have replaced the pads and straightened the rotors to within 5 thou of runout so it shouldn't be the brakes. rides perfectly smooth until i hit the brakes and then it shakes so much that my alignment moves (after repeated braking). any thoughts on this? i've heard it might be my wheel bearings, but they only have like 25,000 kms on them. also been told it might be the bushings inside my front forks.
On a side note, there is also a ringing noise whenever i lean the bike at 80km or more. not sure if this is involved with the shudder or not. any help would be appreciated!
