Cadet Beginner Class

Welcome to the fast and fun world of karting—Cadet Beginner is where it all begins!

Designed especially for our youngest drivers and first-time racers, the Cadet Beginner class is the perfect introduction to karting in a safe, supportive, and exciting environment. It’s all about learning the basics, building confidence behind the wheel, and having a blast on track!

This class is non-competitive and does not contribute to club championship points—so kids can focus on improving skills without the pressure of racing results.

Eligibility:

      *Minimum Age: 6 years

      *Maximum Age: Up to their 13th birthday

      *Special dispensations may be granted by the MKC Management Committee.

Progression to the next class will be based on:

      *Consistent lap times of 46 seconds or less  (subject to change)

      *Meeting the age criteria for the next class

      *Demonstrated driving ability and track awareness

     *Endorsement from the Junior Development Officer and Mgmt Committee

If your child is ready to take their first steps into karting, Cadet Beginner is the perfect place to start the engines!
