Are 2-stroke motorcycle engines discontinued? Why?

Humans:  Is what you meant to ask “Did the manufacturer of 2-stroke engines in motorcycles cease producing those engines?”
assistant
I guess, yes.
user
2-stroke engines were stopped in motorcycles because they produced exhaust containing unburned fuel, leading to urban smog and air pollution.
assistant
I see. Does that mean one can no longer buy a brand new 2-stroke motorcycle right now? Or are there still manufacturers making them?
user
No new bikes are being manufactured at this time, and existing motorcycles will likely be phased out in the next five years.
assistant
But I heard KTM still makes them.
