Types of Kart Racing You May Not Know About

Kart racing has different forms, depending on the kind of kart you’re riding. This makes it a safe and balanced environment for drivers looking for a similar experience. After all, you wouldn’t want your 12-year-old on the same drift track as veteran drivers. While go-karting is typically a fun and enjoyable experience, that doesn’t mean it’s a free-for-all activity. It’s surprisingly strict when it comes to grouping similar drivers together as a safety precaution.

Go-karting types will depend on a person’s driving level, age, and engine brand. This allows participants on the track to run at similar speeds without being at a disadvantage. This streamlines expectations on the track and ensures that the right drivers handle the appropriate karts.

In this article, we’ll share four types of kart racing you can join!

1. Kid Kart Class

The kid kart class is the starter classes of starter classes, where your young ones can enjoy go-karting at the ripe age of seven and below. Since toddlers will be on the racetrack, the capacity of engine powers is limited to 50cc two-stroke engines. This kart racing class also limits top speeds to 30 mph for everyone’s safety.

2. Cadet Racing Class

This category is a step above the kid kart class, allowing kids between seven and 12 years old to drive cadet-sized chassis common to IIAME and RoK engines. Drivers usually handle a 60cc two-stroke engine that can run up to 60 mph. Karting clubs and venues usually split these subclasses into junior, intermediate, and advanced categories for the drivers’ benefit.

3. Junior Kart Racing Class

Another variant of the junior race car driving class is the 125cc tag karting class. While it covers drivers between ages 12 and 15, it’s also fit for younger adults above 15 years. This is because it promotes competitive racing guidelines for karts that run with a 125cc two-stroke engine, allowing them to run up to 80 mph.

Depending on the karting club’s guidelines, junior kart racing classes also have subclasses like cadet racing classes. This creates a fair environment for drivers with more experience behind the wheel, even if they’re running the same engine brand.

4. Shifter 125cc Karting Class

The 125cc shifter class is a great way to enjoy the speed of the track, making it a favorite of drivers who aim for maximum speeds of 80 mph and above. Since it’s a competitive environment for go-karting, only intermediate or advanced level drivers are allowed on these sprint tracks.

5. Masters Racing Class

Who says go-karting is just for children and young adults? The masters class pools drivers 32 years and above to run rare 150cc engines. This makes for an exciting event for spectators to watch full-grown adults duke it out on the track.

This class is split into different weight variations, mainly through heavy and light divisions. Additionally, kids that can’t fit in their weight categories are permitted to join the master class, depending on their driving experience.


Because of COVID-19, it has been difficult for kart drivers to find a COVID-safe outdoor venue to enjoy their hobby. Thankfully, many establishments are adapting to their customers’ needs by adapting to modern business practices. This makes it possible for go-kart drivers in different classes to experience the feeling of being on the track!
