I was doing a google search, this thread was how I found this new forum...

Technically, the Whizzers are (I think) 127-128 cc, and the "technical" way they are getting away with non-registration is the lack of a transmission.

One of my customers has 2 Whizzers, a Kawasaki 1000 and a GEBE system, which is the one he uses for his health, he's putting the Whizzers up as a future collectors item, they are the deluxe ones that go for around $2,200.
