They are not dents . Looks like a huge ill conceived art project. The "dents" appear to be a duct - for post apocalypse rocket launchers or zombie shredders or some such stylistic BS.
The dead giveaway is the rinky little 250 motor, USD forks and clown shoes. It is not a motorcycle - it's an art piece. It is not relevant to anything on this site, but interesting to see what they are doing.
One disconnect we often see in bike projects is that "builders" typically focus on the look because they have no engineering background and what they don't get (in general) is that in a real motorcycle design studio, the builder needs to have engineers to work out what will work and what won't.
Our current crop of stretched swingarms and dented tank, swapped wheels and forks guys have no idea how a motorcycle works or what is safe and what isn't but they all believe that they are entitled to make whatever changes they want to make and anyone who doesn't like it is a hater. That's our narcissistic selfie world.
With these guys, we have no background to know what they are doing or why, so there is no context in which to review the work. If they would like to tell us more about the project and why they are doing it, I'm sure it would help. .................
