How about going Chinese??
I would consider LINHAI. Quality controlled by Yamaha, good build quality, and affordability.
First there is the Turin which is 178cc but a very ridable scoot for a reaonable price. It is air cooled and not everything that you are looking for, but its a really nice scoot.
But I did a little research for you. You can get a LINHAI Aeolus 260 apparently brand new. They are 2008s! For some reason they were found in a warehous??? Anyway check this out.....

This scoot seems to be everything you are looking for.
I do NOT know if these are still available but it looks like they are.... $2,699
Good Luck!
