They have them on display at the International Motorcycle Shows. I have to say, they are very cool!
A lot of us think that $25K is a lot of money for a bike, but that is the average price of a boring, ho-hum new car these days. There are lots and lots of people that can easily afford a $25K motorcycle. An awful lot of Harleys are that much, and what does a Goldwing run? You see lots of those on the road.
Actually, to me the $25K for the H2 seems pretty reasonable, considering the technology involved. The equivalent car would be way over $100K.
As far as someone buying one sight unseen, there is a very strong appeal to many people to have the latest, newest thing. I don't think Kawasaki will have any problem selling them.
