Whether you’re looking to groom the next Formula 1 star or just looking to enjoy motorsports with the entire family and your young driver is age 5-8, the Kid Kart class is for you.  With safety and fun the first considerations, the purpose of the Kid Kart class is to introduce young drivers to the fundamentals of karting.  Accordingly, many of the mechanical variables are fixed so that the emphasis is on working with the driver rather than the equipment.  Everything from engine to gear ratio and tires are specified for all competitors.  At some clubs the kid kart class is a ‘participation only’ class with no awards for finishing position, just a participation award.  Other clubs consider the class like any other and allow kids to compete for points championships.

While many of the Kid Kart class rules are the same across the country, rules do vary by club so it’s always a good idea to check with your local club or track operator for their specific rules.
