As 2-stroke architecture, they'll pretty much run forever as long as you feed them the appropriate ratio and blend of oil that mixes with the fuel. The fuel system itself is like a muscle; needs to be in steady use to prevent headaches from developing (especially since mix left to sit accelerates the turning to goo), and the engine assembly is engineered to live at full throttle.
For me: rear tire every 4-6 months. brake shoes maybe once a year, chain can go anywhere from 6 months to a year. Just depends on make of machine, 3rd party materials, and how far/ how hard you ride (I ride mine like they're stolen, actually did lose one once but recovered it a week later: taught me to ditch cable locks, now have a "Giant" side-tumbler U-lock that's held up 3 years so far. Some people use tow chain)
I already daily 2-stroke stuff that's grandfathered in. No smog, no tags and 60 MPG on a bad day

"Vintage" mopeds (my current 3 are all mid-late 2000s TOMOS bikes, built in Melania's native country)
