MY SON WAS KILLED IN A CRASH ON I-270 IN COLUMBUS OHIO AT THE SR 315 INTERCHANGE. ACCORDING TO AN EYEWITNESS HE HAD JUST PASSED HER ABOUT 70-75 MPH, IN THE THIRD LANE FROM THE BIRM OUT OF 5. BEGAN STRUGGLING WITH CONTROL, SHE SAID THE REAR OF THE BIKE WAS SHIMMYING. THE LOSS OF CONTROL GOT PROGESSIVELY WORSE, HE CROSSED THREE LANES OF TRAFFIC AND CRASHED INTO A GUARDRAIL REAR END FIRST. HE WAS KILLED INSTANTLY. I HAVE SINCE SEEN MANY COMMENTS ABOUT DUCATI MONSTER, AND MOTOTARD 1100'S EXHIBITING WHAT IS CALLED "HIGH SPEED WOBBLE AT 75 TO 80 MPH. I AM CONCERNED THAT THEY AMY BE PLACING THEIR RIDERS AT GRAVE RISK. I WOULD LIKE TO KNOW IF THIS IS BEING INVESTIGATED, OR IF IT WARRANTS AND INVESTIGATION, TROOPER DIEHL OF THE OHP INFORMED ME THAT HIGH TOXICOLGY WAS NEGATIVE, AND THERE WAS APPARENTLY NO ROAD DEBRI THAT WOULD HAVE LED TO THE CRASH. HE SAID THAT IT IS CLASSIFIED AS AN UNEXPLAINED LOSS OF CONTROL. HE WAS WEARING A HELMET AND HE WAS AN EXPERIENCED RIDER. HE WAS 25 YEARS OLD AND A SGT IN THE MARINE CORP RES. WITH H&S COMPANY OUT OF BROOKPARK OHIO.
