I saw one a couple of weeks ago. I didn't know what it was until I saw someone post it. It was green like that too. It had an exhaust on it and sounded odd but again it's a 250.

Which I bet that thing would be awesome for shooting around downtown/midtown Atlanta. Probably fairly nimble but still looks cooler than a Vespa. But I'm 220lbs and 6' tall so it wouldn't be powerful enough for me. Especially since all my friends ride Litre bikes.
