Usually the fastest way to get a woman to avoid something is to say it is perfect for them. I've never seen a woman riding a "small" bike.
By the way. Honda has a new 500cc fuel injected bike that comes in 3 styles coming in 2013. Perfect beginner bike or commuter that won't get boring anytime soon. I'm pretty much set on an sv650 but I might go for the Honda 500 if I like the reviews.
