Here's the proposed settlement for the Streetfighter, it's a real laugher...
2009-2011 Streetfighter Class Vehicles: Fuel tank expansion on these models can on some motorcycles cause the painted, exposed tanks to contact the upper triple clamp3 and the radiator cap.As necessary to address any such problem, Ducati will install a newly-designed fuel tank with slightlyreduced dimensions to accommodate expansion and prevent such contact. (Id. I.6.d.; III.F.)Sorry I don't have any info on other models with expanding plastic tanks...
