Note: The age needed for every class will rely on the region; the numbers stated above are generally true in the United States.

Kid Karts:

As the name recommends, this class is for children, usually of ages five to seven. At this age, they’re frequently simply learning the basics of driving and having a great time doing so! Like in any other sport, embarking early is a huge benefit.

The kart’s chassis utilized for this class is 1/2 the size of an adult go-kart, and the engine is a fifty cc two-stroke engine. A brand new engine and chassis for this class will charge around three thousand dollars combined. But purchasing them second-hand will save you much cash (and is suggested).


It’s one step up from child go-karts and more competitive. Frequently, the age group competing in this class is eight to twelve-year-olds. But relying on where you live, it may differ widely. For instance, in a few European countries, the cadet class is for seven to ten-year-olds.

The engines utilized in this class are frequently sixty cc, and the go-karts are almost 3/4 the size of full-sized go-karts. The engine and kart will need much more maintenance than kid go-karts. A new engine and chassis for this class will charge around 4000 dollars to 4500 dollars combined.


This class is for early teenage drivers (thirteen to fifteen). Go-karting can become really competitive for this class. It’s the first time that the driver will have a full-size go-kart, and it can really be a challenge switching from 3/4 size go-karts to cadet go-karts. There frequently are numerous engines to compete with from it onwards, the most well-known being 100cc.

If you live in the United States, LO206 engine class may also be accessible for juniors, and LO206 is an awesome cost-effective way of entering for novices. A brand new engine and chassis for this class will charge around 5000 dollars to 8000 dollars combined, relying on the engine you make use of. Engine rebuilds and Maintenance would not be cheap either.


Frequently, this one is for anybody above the age of sixteen. It might differ depending on where you live. The go-karts are full size, as you would expect. 125cc engines are the most well-known for it. Both Shifter engines and TaG style are very common. In the US, LO206 is also well-known for this class.

A 125cc 2-stroke engine and a brand new chassis can charge anywhere between 5000 dollars to 10000 dollars. But do not worry about the cost of a new engine and chassis. If you purchase a second-hand engine and chassis, then the budget you will have to compete in the local leagues is roughly 5000 dollars for two-stroke 125cc TaG engines; it comprises the tires, maintenance costs, race entrance fees, and piston change costs. That is not really inexpensive, but unluckily, racing sports are costly to compete in, and karting is one of the cheapest choices.


This one is for anybody above the age of thirty. Aside from that, it is the same as the senior class in terms of engines utilized and the price of competitive racing.
