Kart racing - online puzzles

Kart racing or karting is a variant of open- wheel motorsport with small, open, four -wheeled vehicles called karts, go-karts, or gearbox/shifter karts depending on the design. They are usually raced on scaled- down circuits. Karting is commonly perceived as the stepping stone to the higher ranks of motorsports, for example Ginetta Juniors, FIA Formula 4, FIA Formula 3, FIA Formula 2 and FIA Formula 1, with former F1 champions such as Nico Rosberg, Ayrton Senna, Lewis Hamilton and Michael Schumacher beginning their careers in karting.

Karts vary widely in speed and some (known as Superkarts) can reach speeds exceeding 260 kilometres per hour (160 mph), while recreational go-karts intended for the general public may be limited to lower speeds.
