With 400cc and over - you can keep up with traffic anywhere.
I'd go with Suzuki, Honda, Yahama or Piaggio. Maybe even a Kymco if you're willing to do the prep work.
I’d buy a Vespa LX 150 cc model but shortages and the high price to start with conspire against that idea. I may end up with a Kymco People S 125 instead.
