Thank you Frank. So the belly pans go all the way under the engine and the other are only in the front.
The way I understood these were just different designs of belly pans, except for the obvious ones that go completely under the engine like on motocross bikes or similar off road - I thought these are just engine protectors that go under the engine! haha
I most likely want be using any of these, and probably will call a belly pan a chin scratcher and vise versa again. LOL
