Owner report 10277622 · 2009-07-21 (July 21, 2009)
MY MOTORCYCLE HAS A PLASTIC GAS TANK WHICH HAS BEGUN TO EXPAND. THE OUTSIDE DIMENSIONS OF THE TANK HAVE INCREASED AND IT NOW DOES NOT SIT CORRECTLY IN THE FRAME, THE HANDLEBARS HIT IT ON TURNING, AND IT PRESSES AGAINST THE IGNITION SWITCH. PREVIOUSLY IT OPENED AND CLOSED WITHOUT PROBLEMS, NOW I HAVE TO WEDGE IT AGAINST THE IGNITION SWITCH TO CLOSE IT. THE RUBBER MOUNTS NO LONGER SIT ON THE FRAME. I HAVE GOTTEN A REPLACEMENT TANK FROM MY LOCAL DUCATI DEALER SHIP BUT THEY STATED THAT IS WAS ONLY A TEMPORARY FIX AND THAT THE PROBLEM WOULD MOS…

PREVIOUSLY IT OPENED AND CLOSED WITHOUT PROBLEMS, NOW I HAVE TO WEDGE IT AGAINST THE IGNITION SWITCH TO CLOSE IT. I HAVE NOT SIGNIFICANTLY MODIFIED MY MOTORCYCLE EXCEPT FOR AN AFTERMARKET EXHAUST AND SOME COSMETIC CHANGES. I HAVE MADE NO MODIFICATIONS TO THE FUEL TANK OR FUEL PUMP.

JUST AFTER SERVICING THE MOTORCYCLE AT 600 MILES IT STALLED WHILE SHIFTING INTO GEAR. THERE WAS NO PROBLEM PRIOR TO THE SERVICE. THE MOTORCYCLE TOTALLY SHUT DOWN WHEN SHIFTING INTO GEAR.

I HAVE ONLY RIDDEN IT THE ONCE AND WILL NOT RIDE THIS MOTORCYCLE NOW BECAUSE OF THE SAFETY CONCERNS. I HAVE BEEN IN CONTACT WITH THE DEALER, BUT HAVE NOT RESOLVED THE PROBLEM.

Owner report 10362668 · 2010-10-27 (October 27, 2010)
THE FUEL TANK ON MY 2007 DUCATI S4RS HAS EXPANDED TO THE POINT IT COULD NO LONGER FIT ON THE BIKE. THIS TANK WAS REPLACED UNDER WARRANTY FOR THE SAME PROBLEM LESS THEN A YEAR AGO. THE ISSUE APPEARS TO BE A PROBLEM WITH THE PLASTIC FUEL TANK REACTING THE FUEL. IT MAY BE RELATED TO ETHANOL IN THE FUEL. THE COMPANY CONTINUES TO REPLACE THE TANKS UNDER WARRANTY BUT I BELIEVE A RECALL SHOULD BE STARTED SINCE THIS PROBLEM CAN LEAD TO A TANK BEING UNLOCKED ON THE FRAME WITHOUT KNOWING IT. IN ADDITION THE FUEL LINES CAN LEAK DUE TO THE SHIFTING O…

TL*THE CONTACT OWNS A 2007 DUCATI MONSTER S4RS. SINCE OCTOBER OF 2006, THE CONTACT'S ENGINE HAS BEEN STALLING. WHILE IDLING AT A STOP, THE VEHICLE'S ENGINE FAILED. THE CONTACT STATED THAT THE FAILURE OCCURS BETWEEN 0 AND 25 MPH. ONCE THE VEHICLE ACCELERATES BEYOND 25 MPH, IT OPERATES NORMALLY. THE CONTACT HAS TAKEN HIS VEHICLE IN TO HAVE THE THROTTLE POSITION SENSOR AND THROTTLE BODIES/SERVO MOTOR REPLACED BECAUSE WATER WAS SEEPING INTO THE CONNECTION AND CAUSED IT TO CORRODE. THE VEHICLE WAS KEPT FOR TWO AND A HALF WEEKS TO BE REPAIRED, …

FUEL TANK IS PLASTIC AND APPEARS TO HAVE A REACTION WITH THE ENVIRONMENT THAT IS CAUSING THE MATERIAL TO SWELL IN ALL DIMENSIONS. THIS CAUSES THE TANK MOUNTING TO BECOME HIGHLY STRESSED, UNSEATED AND UNSTABLE. THE TANK IS INTERFERING WITH THE STEERING. *TR

Owner report 10353209 · 2010-08-31 (August 31, 2010)
FUEL TANK HAS INCREASED IN SIZE AND SHAPE IS DEFORMED. TANK SUPPORTS TO FRAME OF MOTORCYCLE ARE PUSHED AWAY FROM FRAME. TANK IS IN CONTACT WITH STEERING HEAD OF MOTORCYCLE. LATCH TO REMOVE TANK IS JAMMED INTO IGNITION SWITCH. THESE ISSUES ARE A SAFETY CONCERN IF LATCH OR TANK SUPPORTS FAIL. LATCH IS LOCATED IN FRONT OF TANK. TANK COULD BE LIFTED UP AND BACK WHILE RIDING IF LATCH FAILS. TANK IS MADE OF PLASTIC MATERIAL. SIZE INCREASE AND DEFORMATION APPEARS TO BE CAUSED BY ABSORPTION OF WATER/ETHANOL DUE TO PHASE SEPARATION OF GASOLINE AN…

Owner report 10348525 · 2010-08-10 (August 10, 2010)
DUCATI MOTORCYCLE GAS TANK EXPANDING. EXPANDED SO MUCH THAT IT WAS NOT SITTING PROPERLY ON MOTORCYCLE FRAME, WAS UNABLE TO UNLATCH OR RELATCH TO BIKE TO GAIN ACCESS TO BATTERY. HAD TANK REPLACE LAST YEAR UNDER WARRANTY BY DUCATI. BUT THE NEW TANK IS NOW EXPANDING AND IT HAS BEEN 1 YEAR. FEEL THIS WILL BE AN ONGOING PROBLEM...GAS TANK IS PLASTIC. OLD TANKS WERE METAL, NEVER EXPERIENCED THIS BEFORE. SEEMS TO BE RELATED TO ETHANOL IN THE GAS, AND THE PLASTIC GAS TANKS. I BELIEVE DUCATI NORTH AMERICA NEEDS TO GO BACK TO RE-DESIGN TANKS, POSS…
