Motorcycle and Scooter appreciation

After a frustrating ride with a low pressure rear tyre due to two petrol stations pumps not inflating my tyre I'm half seriously looking at getting new wheels for my air cooled Triumph.

Where do I start?

What I'd like is:

• tubeless
  
• Alu rim / lighter wheel over the steel ones on there.
  
• probably the same colour - black rim, silver spokes, black hub... altho I'm wondering if black spokes would require less cleaning
  
  

Size wise I'm agnostic. I sort of like the old fashionedness of my scrambler. I know some people put more modern sizing on them, but honestly idk enough to make an informed call.

I had planned at some point to do a tubeless conversion, but that is just totally unrealistic any time soon.

Cheers.
