This is a good idea.
Best tool

This is how I would do it, similar to @mikeS' suggestion:
1) Get a wood plate large enough to cover the circumference, and place just underneath the flat portion of the plastic part
2) Screw the plastic part to the wood plate so that it stays in place while drilling
3) Clamp the wood part
4) Drill with hole saw for metal. Slowly.
5) Finish with sanding
That could work. When I mentioned chainsaw, I actually had one of these in mind ...

It’s comical reading all these ideas and it shows virtually no one actually works with tools these days! 🙄 Proper tool would be an air belt linisher as you have perfect control and it puts a perfect curve in. Failing that and you could heat up a knackered screwdriver and burn the basic shape out.

What’s an air belt finisher? I asked a metal shop if they could do it. No dice. Also couldn’t suggests a tool. Then I asked here and voila! Thanks all for the advice
That attachment is designed for wood carving rather than precision cutting a circle, especially in thin plastic.That could work. When I mentioned chainsaw, I actually had one of these in mind ...

It’s also one of the more dangerous wood carving power tool attachments.
The cutting task is rather minor, so I’d avoid power tools. A coping saw to cut close to the line then emery paper wrapped around a tubular surface not too much smaller than the desired radius (any appropriately sized household item) to finish up to the line would be my approach. Gently, gently.

This is the electric version ‘linisher’ as most people won’t have air lines to hand.
Seems like the collective sense of humour has evaporated.
I didn’t know whether to laugh or cringe in fear that someone might take you seriously
Well, I actually have one of the dreaded Lancelot death machines; I sometimes make chairs as part of my other hobby. It’s perfect for dishing the seats. I also have two regular chainsaws, and know how to use them and maintain them - Canadian, eh. I also used to ride a Kawasaki rubber-frame H1 at insane speeds when I was younger and more bouncy. I still have all my limbs with all digits still firmly attached. I wear proper protective gear, and think about what I’m doing. I guess I’m also gonna have to start using large numbers of emojis when joking about using power tools in inappropriate ways, to save the naive from serious harm.

Sturgeon’s safety tip of the day - don’t put your bare fingers on the red parts when cutting and welding with a torch. I’m serious. DON’T DO IT!
As for the cutting job in question, I’m with you @Panzermann , A coping saw and a bit of sandpaper would be my choice. Save electricity and the exercise is good for you.

Yes 😉, and some (include myself) would say “Krad“ wich means Kraftrad. Never say bike because that is a bicycle. You see it‘s arbitrarily complex and we germans love to categorize everything 😄.
I believe what in English is called a moped, in Germany is called "ein Roller". Stimmt das @Lee089?
