Karting chassis are constructed of steeltubes, which are made in different sizes depending on what class it is made for. Chassis with 28mm in diameter are usually constructed for the smaller karts and both 30mm and 32mm in diameter are ment for bigger classes in the national and international competitions.

In comparison to cars, karts are much smaller and lighter and the only protection karts have are the plastic boxes and accessories around the kart. And the fact that karts are much smaller and lighter.

Below you will see how a kart looks like nowadays. There are of course many manufacturers that are constructing their own chassis, actually there are some minor detail differences in between the chassis, but overall they seem to look the same.

Some of the Karting chassis manufacturers:

• CRG
• Maranello
• Tony-Kart
• Intrepid
• Energy
• Swiss-Hutless
• Birel
• Haase
• PCR
• Gillard

Kart chassis are filled with setup
possibilities. In order to choose the
most optimum settings, the
weather, track and tires are some
of the factors that needs to be
considered.

The difference between dry and wet track is tremendous when it's about chassis setup. Lets say it starts to rain, obviously tires needs to be changed to wets, air pressure needs to be raised, approaching a higher centre of gravity by raising the seat or chassis, adjust front-end to get as much steering as possible. It's quite a lot of changes and there are usually no time for every change, because of the limited time between races.

All the tracks are different and have their own characteristics. In one hand surfaces may be flat or rough, it could have new asphalt which could be very slippery or there could be a track which has a lot of rubber which gives a lot of grip. Track profile may also be an important part on chassis setups, because usually there are no specific chassis setups that works best for every particular track.

There are also different tire compounds and manufacturers, that may cause some small adjustments in chassis setups. But by the rules only one kind of tires are allowed to use per class. Some international classes may have the possibility to use different types of tires, but the compound is usually the same.
