text: It seems a bit weird you calling yourself ScootDude when you don't have much of an idea about what you from a maxi scooter apart from the ability to go on motorways. Any one of the scooters on your list can handle our motorways. It's your money you're spending so doing a bit of legwork round showrooms to look at the scooters you're interested in, and maybe getting a demo ride or two would give you more idea than asking on a forum.
  The Burgman 400 should be a good machine, but if you do your own maintenance you may get a little aggravated. You have to pull off more of the body panels to do what I consider routine maintenance.
  Kymo 500 - I have owned a Kymo 250, and if the other models are similiar I will just say that suspension is rough. I didn't mind mine for short rides, but didn't want to take it on longer rides. And the maintenance schedule for Kymco's seems to be more frequent than other models.
  The Silverwing compares very favorably to the Burgman 650, but the big Burgman also suffers from he same aggravations with maintenance. And changing the transmission oil was really a chore - I know, owned one for a while.
