I TOOK THE BIKE TO THE DEALER WHO SUBMITTED A CLAIM TO …

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 TAN…

THE PLASTIC FUEL TANK ON MY 2005 DUCATI S2R 800 IS SWELLING/DEFORMING. THE SWELLING IS CAUSING COSMETIC AND STRUCTURAL PROBLEMS WITH THE FUEL TANK. COSMETICALLY, THERE ARE RIPPLES AND BULGES ALL OVER THE TANK. STRUCTURALLY, THE TANK HAS SWOLLEN SO MUCH THAT THE HANDLEBARS HIT THE TANK AND STEERING IS LIMITED. THE TANK HAS ALSO SWOLLEN SO MUCH THAT THE TANK SUPPORT PADS ON THE UNDERSIDE OF THE TANK BARELY MAKE CONTACT WITH THE FRAME OF THE MOTORCYCLE. ADDITIONALLY, THE TANK HAS SWOLLEN AROUND THE IGNITION AREA SUCH THAT THE IGNITION FASCIA …
