Wrenching

Sure, the Troy Lee Designs/Red Bull/KTM guys want the extra air in the airbox, but that doesn't mean that they want to let in roost and debris. They glue the filter covers over the inside of the side cover.

The tie-down? That's to compress the suspension, linkage, and subframe as it's tightened down. That way they get more accurate measurements on sag.
