I can't watch the video right now (God knows why...), but from what you people tell me I know what to expect.
I saw superkarts in action once. They didn't even have a 1100 engine, but were damn fast. Those superkarts did have a manual five or six speed gearbox. I saw them at the TT circuit in Assen where they lapped the track faster than the MotoGP bikes. :shock: I was told superkarts could reach speeds of up to 300 km/h.
