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…

THIS MAKES THE FUEL TANK NOT SECURED TO THE FORWARD PART OF THE MOTORCYCLE.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
