AS I WAS ON THE FREEWAY AND WE WERE SLOWING DOWN DUE TO TRAFFIC, GOING ABOUT 25/30 MPH, I APPLIED BOTH FRONT AND BACK BREAK. MY FRONT BREAK LOCKED UP AND BOTH ME AND THE BIKE WENT DOWN. I AM AN EXPERIENCED RIDER AND THE PERSON WHO WAS RIDING NEXT TO ME HEARD THEM LOCK UP WAS SHOCKED. THERE IS AN ABS SYSTEM ON THIS BIKE AND THIS SHOULD NOT HAPPEN EVER.
