The Shifter Kart is fast, and more demanding than a regular racing kart. As the name says, the karts have gearboxes with 5 or 6 gears, depending on the kart.
They are mainly used for sprint kart racing, on road course tracks. But they are sometimes found on ovals, but not often, and it would not be normal to see them on them.
A special thing about these is that they are one of the more demanding types of karting. You have to worry about cornering, and shifting at the same time, so this is usually the class for more professional type races, as well as Formula Car racers for practice in the offseason
A Shifter with Water Cooled Engine
Since they are mostly raced on sprint tracks, the chassis are open straight chassis. They are designed to handle left and right turns.
They have bodywork that consists of two side "pods" and a small low-profile front nose.
If the engine for the shifter is water cooled, it will have a radiator to the left of the kart's seat.
Hondas are the popular engine in America
