The kit seems pretty lame, since it's essentially a bunch of plastic that you bolt on over your ordinary scooter. (If you look closely at the above photo, you can see the actual tire peeking out from the bottom of the black plastic fake-tire shell.)
Plus, the prices aren't much of a bargain. Even if you already have a Fusion, the kit alone will run you ¥630,000, or about $6,000. A Fusion itself lists for only about $5,000 new.
I'll hold out until we can buy something more like the actual working prototype I posted about here.
