Take a Hayabusa 1300cc engine and put it a couple of inches off the ground on a go-kart chassis and you get something really fast. Depending on what year this engine is it has 151 hp – 171hp. I don’t know what the weight of this go-kart is but I would assume it has a very sick power to weight ratio. Creators website. The videos speak for themselves.
