I'm assuming there is an undertray part of something that the 2 underneath hole fixings in the bodywork go into when using race bodywork ?
If it is the Ducati race plastic, the fitting instructions, https://media.ducati.com/EPCResources/ATTACHMENTS/3E/3EFCD12AE7C3D8F71DADE8B71B53C3F8.pdf, show the standard bodywork with the seat release lock in it still fitted. Andy
