Thanks for posting your ride.

Regarding the seat/airbox cutouts... I would not lift the bike by the seat cutout areas. The seat is held by a single bolt and the seat base can flex easily if you grab by this cutout area. IMO this cutout functions more as an air intake for the airbox. When lifting the bike, it is better to grab under the rear fender where it joins the subframe (near the silencer). There is a comfortable grab point here and you can swing the bike up on a workstand easily.

EDIT:
Here is a pic showing the lift locations.
