2012 SUZUKI DR650 — ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:MANIFOLD/HEADER/MUFFLER/TAIL PIPE

I LOST CONTROL OF MY BIKE IN LOOSE DIRT AT ABOUT 15 MPH WHILE OFF ROAD RIDING. THE BIKE ROLLED TO THE RIGHT AND PINNED ME TO THE GROUND WITH THE EXHAUST PIPE WITH HEAT SHIELD ON MY RIGHT ANKLE. ALTHOUGH I HAD A HELMET ON I WAS DAZED AND COULDN'T LIFT THE 400 LBS BIKE OFF MY ANKLE FOR ABOUT 5 MIN UNTIL MY COMPANION LIFTED IT OFF ME. THIS IS A CALIFORNIA DMV COMPLIANT BIKE THAT HAS A CATALYTIC EXHAUST PIPE WHICH IS HOTTER THAN A STANDARD BIKE FROM ANOTHER STATE. I SUSTAINED A FOURTH DEGREE BURN TO MY ANKLE INTO THE BONE. I'VE HAD TWO SURGERIES AND MY LOSE MY RIGHT FOOT. IS THERE A NHTSA OR OTHER AGENCY EXHAUST HEAT STANDARD THAT THE MANUFACTURE MUST COMPLY? IF SO WHERE MAY I FIND IT? MAY I HAVE AN ENGINEER REVIEW THIS WITH ME? I FEEL I SHOULD NOT HAVE BEEN SO SEVERELY BURNED FROM A EXHAUST PIPE WITH A HEAT SHIELD ON IT THIS IS A SAFETY ISSUE, PLEASE ADDRESS MY CONCERN. THANKS YOU *TR
