My oldest son Frans have started with karting. He have now taken a licens after theoretical course and a test drive in Skövde, (the only 6 year old in his school to have this). He is now allowed to drive on all tracks in Sweden. The kart is a CRG 950 chassi with Raket 60cc engine. Here is some pics and videos. He is driving in the Cadetti class.
