More art than function.
There is so much wrong it isn't funny.
In the video the first thing that is obvious, right silencer is bouncing around so either it isn't mounted properly or bracket has already broken.
The footrest plate is also swing arm outer plate, Oh, don't need that then
'Lightening holes' in brake drum - they are for extra airflow when racing - cooling holes
Fork brace - why bother I only ride it slow so people can see me
As for attention to detail, cheap pods with seam not rotated out of sight, seat dropping at front
I could probably point out a lot more but I stopped watching
At least it doens't have the damn stupid Firestone tyres and suspension so low wheels hit frame
