So today when I took the bike out on the highway, I had to brake hard in a straight line from approximately 100 km/h. As I squeezed the front brakes firmly the windscreen would shake and vibrate. Also, I can feel a pulsing sensation with my braking hand. At 50-60 km when I brake, there is no noticeable shaking. Do you guys have any insight at what could be causing this issue? There is no record of any accidents on this bike and all parts are oem.
