NHTSA Complaint #10873654 — 2010 TRIUMPH THUNDERBIRD

TURNING RIGHT FROM A SIDE STREET ONTO A MAJOR ROAD, I BEGAN ACCELERATING AND THE THROTTLE BECAME INOPERATIVE, SNAPPING IMMEDIATELY BACK TO IDLE SPEED. SUBSEQUENT TURNING OF THE THROTTLE GRIP HAD NO EFFECT. THERE WAS TRAFFIC ON THE MAJOR ROAD THAT FORTUNATELY WAS ABLE TO SLOW DOWN IN RESPONSE TO MY UNEXPECTED AND SUDDEN LOSS OF SPEED. THE ATTACHMENT FOR THE THROTTLE CABLE SNAPPED OFF OF THE THROTTLE GRIP ASSEMBLY. MY GRIPS WERE AUTHENTIC OEM TRIUMPH ACCESSORIES - HEATED GRIPS. APPARENTLY, THIS IS A NOT AN INFREQUENT FAILURE. TRIUMPH HAS SUPERSEDED THE ORIGINAL ACCESSORY KIT WITH A LATER PART NUMBER, BUT COULD NOT TELL ME IF THE SUPERSESSION INVOLVED A MATERIAL OR DESIGN CHANGE FOR THE THROTTLE GRIP ASSEMBLY. THE THROTTLE OPERATED PERFECTLY AND THEN FAILED WITHOUT ANY WARNING. THERE WAS NO EXCESSIVE FREEPLAY IN THE THROTTLE LINKAGE, NOR DID IT BIND IN ANY WAY PRIOR TO THE FAILURE.
