The GoKart is part of the heavy variety, is extremely stable and has a high fun factor. Man (n) Note the rear fender of sheet metal (not plastic and Elaste) and the "wide tires". On the wings can again 2 kids sit, without burning your ass on melting Plasik :) The tires also put tough terrain off loosely. All in all, a heavyweight, who are struggling with the children, and an investment in a certainly long durable Funkart! And when the thing times is not interesting for the kids, dad can indeed grow a motor, enough steel is there to secure a good holder.
