Unfortunately I don't think she'd go for a dual sport. For one, off the lot they're more expensive, and she likes the sports bike look. This is going to be her primary mode of transportation so I'm thinking of trying to talk her into getting a cruiser instead.
Incidentally, at work today I asked a coworker about his bike and he offered to sell it - a Suzuki LS650 (2002) for $800. It's in good mechanical condition and has about 6k miles, says it's been garage kept and it looks it.
A 650 is probably a bit much for a first bike but I'm tempted to pick this up for myself if nothing else.
