Well I passed a guy doing 10 under the speed limit. As I went around him my front tire started shaking bad and I seen enough youtube videos where this happens and someone spills. Luckly I got control of the bike and went on my way. I ran the bike up to about 120mph to see if it do it again and nothin, went around a corner at 70 and nothin.. I don't think I was doing anything out of the norm passin this guy, maybe I yanked the throttle to fast but some feedback from ya'll I would appreciate so I know what I did wrong.
