Micro kart
A micro kart is a small, one passenger mini go-kart. These karts typically have 2-stroke engines, ranging in size from 22.5 cc to 85 cc, and putting out anywhere from 1.2 HP to 20 HP.
Types
Lower class micro karts
The lower end karts have solid rubber tires of about 4.5 to 6 inches diameter and weigh about 50-60 pounds. They typically have motors in between 22.5 and 40cc, but motors up to 57cc can be purchased from aftermarket sources. These karts typically travel in between 20 and 30 MPH. These karts are primarily used by private parties for recreational riding, but are also raced in racing organizations such as the ISA (International Scootercross Association). Two good examples are the Bladez Powerkart, and the Goped Go-Quad.
High power micro karts
The larger class karts have 9" or 10" pneumatic tires and weigh in between 60 and 80 pounds. They typically have water-cooled motors ranging from 40cc to 85cc, and travel in between 40 and 70 MPH. These karts are commonly used in racing organizations across the country.
