The way these bikes are modelled makes that borderline impossible (for you)
The models are exported from a 3D modelling program as a file you can't just move over to another bike folder.
So the only way it is possible is if you get the blend files or the 3ds Max files for 2 different bikes and modify the new body part to fix. And nobody needs these files. They're useless to most people. So you can't do it, your KTM RC8 panels are permanent.
Learn how to use 3DS Max then you can make your own bike and do whatever you want!
