Road Racing came into being when sprint karts began racing on long sports car tracks. It was found that by laying the driver down, out of the windstream, aerodynamics and top speed were greatly improved. As the length of the races increased, there became a need for large capacity, side mounted fuel tanks. Soon the road racing kart had its own distinctive look and purpose. However, in recent years, sprint and sprint crossover classes have been added to improve participation and to give sprint competitors an opportunity to run on the “big” tracks. The sprint road race classes generally run races from 20 to 30 minutes in length. Road races for the enduro or “laydown” karts are usually one hour in length.

They are staged by some of the finest motorsport complexes in the United States. Portland International Raceway, Sears Point, Laguna Seca Raceway, Willow Springs Raceway, and Seattle International Raceway are only a few of the tracks a Road Racing karter can enjoy at a fraction of the cost incurred by the professional race driver.
