Example complaints

“The gas tank on my 2006 Ducati monster s2r has expanded in both width and length. The larger dimensions now allow the handlebars to hit the tank which could cause a loss of control/crash. Another worrisome issue with an ever-expanding plastic gas tank is the fact that it sits in your lap while riding. Not really where I would want a sudden expulsion of flammable liquid onto a hot engine when the tank splits open.”

“Recently found that my fuel tank on my 2006 Ducati monster s2r 800 motorcycle has expanded and is becoming deformed causing contact between latch and ignition switch. Also found that the tank no longer properly rests on the frame.”

NHTSA complaint #10291789, filed 2009-11, 8,000 miles

“I own a 2006 Ducati monster s2r-1000 (purchased new 11/2006), and it has a plastic gas tank that has become distorted from its original shape. My fuel tank has become distorted on the left/ right sides of the tank in the area where my knees touch the tank. There is some type of demformation around the gas cap, which is causing the paint to crack. The rubber pucks, which are on the bottom of the tank, support the tank on the frame. The pucks no longer sit correctly on the frame, and the tank does not sit securely on the frame.”

“Vehicle: 2006ducati monster s2r 1000(not listed in the following list). Within the past 6 months, the stock plastic tank on my motorcycle is expanding and deforming. The tank no longer sits correctly on the frame, the handle bars hit the tank preventing full range of motion. Also the hold-down latch is pressed against the ignition switch preventing proper removal to access the under tank components, battery, air filter. I have not modified my motorcycle, nor it's fuel system or fuel pump, located inside the tank. …”

NHTSA complaint #10276998, filed 2009-07, 2,500 miles

“I have a 2006 Ducati monster s2r1000 with approximately 2500 miles on it. 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 made no modifications to the fuel tank or fuel pump. The bike is completely stock. …”
