i think when you slam on your brakes with out the clutch in your bike will bobble espicially in hard braking. if you put ur clutch in it will stop.

Secondly, don't slam or grab or stab the brake lever...squeeze it. Don't forget to use the rear brake as well. It will greatly improve stopping distance. Thirdly, if this is your first bike (or your tirty first for that matter) spend some time in an open parking lot practicing emergency braking and steeringmanuevers. It may sound silly but it helps...a lot. You'll learn the bikes reaction to severe circumstances (as well as your own). Finally, watch that speed. If you were doing 65mph with stop lights @ 75 feet, you were riding too fast. Ride safe and smile.
