I don't think I would ever buy something like this... For one thing, none of them are remotely big enough for me (you might get 20hp out of the absolute biggest of them, which is I believe about 300cc. I can't ride on the highway with that).
... But I absolutely LOVE that we live in a world where you can go to amazon, click a button, and get a motorcycle delivered to your door for short money (dirt bikes and scooters for as little as $750 with shipping, street bikes for less than $1500 shipped).
