I HEARD SOMETHING ABOUT HIS REAR BRAKES THAT HIS FRIENDS WAS SAYING HE KEPT TELLING HIM TO CHANGE THEM BUT HE WOULDNT LISTEN SO BASICALLY HE HAD NO BRAKES..IM ASSUMING THATS WHY HIS FRONTS BRAKES LOCKED UP AND HE FLEW OVER THE FRONT HANDLEBARS. THERE ARE 2 SPOTS AT THE END OF THE TRACK WHERE YOU CAN JUST SLOW DOWN AND NOT GO DOWN THE END OF THE TRACK. I WOULD THINK HE TRIED TO STOP TOO FAST AND MAKE THE FIRST TURN AND HE HIT THE BRAKES TOO HARD AND HE WENT HEAD OVER HEELS. I ALSO HEARD THE SAME GUY SAYING SOMETHING ABOUT FLUID ON THE TRACK SO I DUNNO, JUST STUFF I HEARD, NOT SURE IF ITS TRUE OR NOT. THE TRACK OFFICIALS SAID HE WAS OK AND THEY WERE JUST TAKING HIM TO THE HOSPITAL FOR PRECAUTIONARY ISSUES.
