That Gixxerkart has massive speed obviously but I am betting it handles like crap and any regular kart would smoke it on a kart track. In that video the thing just smokes its tires and powerslides everywhere. Obviously fun, but not a fast way around the track.

Listen to ShifterKart's advice. Go to Pat's Acres and see who is running what. Then get one of those. I beleive Pat's Acres runs a decent Rotax class so that would be a good place to start.

 

I bet, on a large enough track (full-size) I could pilot that Gixxerkart faster than most any traditional shifter kart.
