IllustrationPLASTIC FUEL TANK IS SWOLLEN OR WARPED MAKING IT HARD TO LIFT THE TANK FOR SERVICE. ALSO, TANK DOESN'T SIT CORRECTLY ON THE FRAME, THE RUBBER FRAME BUMPERS SEEM TO HAVE MOVED OUTWARD ENOUGH TO NOT SIT FLUSH WITH THE FRAME. THIS SEEMS TO BE AN ONGOING PROBLEM WITH NUMEROUS MODELS IN THE DUCATI LINE WITH PLASTIC FUEL TANKS. *TR

I OWN A 2005 DUCATI S2R 800 MOTORCYCLE. MY FUEL TANK HAS EXPANDED BEYOND THE POINT WHERE THE PAINT HAS STARTED TO CRACK AND IT HAS BECOME DIFFICULT TO OPEN THE LATCH TO GET ACCESS TO THE BATTERY AND OTHER COMPONENTS. I HAVE ALREADY HEARD THAT THIS IS NOT AN UNCOMMON ISSUE WITH CERTAIN DUCATI FUEL TANKS. DUCATI HAS REFUSED TO COVER THE TANK DAMAGE AND AFTER SPEAKING WITH THE MECHANIC, HE TOLD ME THAT THE TANK WILL CONTINUE TO EXPAND AND POSSIBLY LEAK MORE GASOLINE AS TIME GOES ON. I DON'T WANT TO IMAGINE WHAT COULD POSSIBLY HAPPEN AS THE TANK CONTINUES TO EXPAND AND GASOLINE CONTINUES TO LEAK. *TR

THE GAS TANK ON MY 2005 DUCATI MONSTER S2R IS EXPANDED AND IS CAUSING PROBLEMS COSMETICALLY, IN ITS FUNCTIONALITY AND WITH MY PERSONAL SAFETY. FIRSTLY THE STEERING STOPS ARE MAXED OUT AND MY HANDLEBAR CONTROLS HIT THE TANK CAUSING A SAFETY ISSUE. THE TANK IS VISIBLY WARPED ALONG BOTH SIDES. THE DUCATI MONSTER S2R TANK SHOULD ONLY HOLD 3 GALLONS WHEN FULL HOWEVER MY TANK CAN CARRY 3.4 GALLONS. THE PAINT IS CRACKING AROUND THE TANK LATCH WHICH IS PRESSING INTO THE CAP AROUND THE ANTENNA PORT. THE CONTROLS HITTING THE TANK WHILE RIDING CAN PINCH A RIDERS HAND CAUSING A CRASH. THE EXPANSION OF THE TANK CAN CAUSE A LEAK OF THE GASOLINE CAUSING NOT ONLY A DAMAGING EFFECT ON THE ENVIRONMENT BUT ALSO A SERIOUS RISK OF FIRE AND INJURY TO ME. ALSO THE TANK CAN CAUSE PRESSURE TO THE REAR SEAT LATCH CAUSING IT TO POP OFF DURING RIDING THUS CAUSING A CRASH AND INJURY. I BELIEVE THE ONLY ACCEPTABLE SOLUTION WOULD BE REPLACEMENT OR REIMBURSEMENT FOR A REPLACEMENT TO BE PURCHASED BY A LOCAL DEALER OR MYSELF. *TR

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 NOT MODIFIED MY MOTORCYCLE EXCEPT FOR SOME COSMETIC CHANGES. I HAVE MADE NO MODIFICATIONS TO THE FUEL TANK OR FUEL PUMP. I TOOK THE BIKE TO THE DEALER WHO SUBMITTED A CLAIM TO DUCATI NORTH AMERICA (THE IMPORTER/FACTORY). TO DATE, I HAVE NOT HEARD BACK ABOUT THE CLAIM. I AM VERY CONCERNED AS TO THE SAFETY OF THIS MOTORCYCLE NOW. THE TANK'S SWELLING HAS MADE IT SO THE HANDLEBARS DO NOT TURN CORRECTLY. IF THE TANK SWELLS ENOUGH, IT WILL SPLIT OPEN AND I AM CONCERNED THIS WILL HAPPEN WHILE I AM RIDING. *TR

1PE10045 · Fuel Leak At Pump/tank Interface
Opened Nov 4, 2010 · Closed Feb 28, 2011
Status: closed (inferred from source dates) · Fuel System, Gasoline:storage:tank Assembly
After opening this PE, we met with subject owners, dealers, and Ducati North America personnel.We learned that the subject leakage is limited to the Multistrada line alone and is unrelated to composite fuel tank deformation.Rather it stems from the inability of the original sealing O-ring to conform to the tank's relatively rough sealing surface.Recall 11V-020 provides a new X section O-ring to address the Multistrada issue and with that recall, this PE is closed for the Multistrada.Meanwhile, unlike the Multistrada, the Monster line fails to exhibit a current safety defect trend and, on that basis, this PE is closed for those models as well.
