Motocross (often shortened to MX or MotoX) is a form of motorcycle sport or all-terrain vehicle racing held on enclosed off road circuits. Motocross is derived from the French, and traces its origins to British Scrambling competitions. The name "motocross" is a portmanteau derived from the words "Motorcycle" and "Cross Country".
Motocross is distinct from other forms of motorsport in having a mass start, where all the riders line up alongside each other, starting simultaneously and racing the race distance. The first rider across the finish is the winner of that "moto"; the number of motos may vary and points are added up to determine the final winner.
Motos vary in duration, measured in time elapsed plus one or two laps, or alternatively a fixed number of laps. Top level racing tends to have long races (e.g. 30 minutes plus 9 laps) while at the other end of the spectrum, amateur races can be as short as 5 minutes. When the designated time duration of the race is complete, a finish line flagger signals via a board or flag to the racers that there are one or two laps left, and the race is finished by a checkered flag.
Motocross tracks are often quite large (a quarter mile) and incorporate natural terrain features with varying amounts of man-made jumps and other features. It is not unheard of for a Motocross track to be made up entirely of hills and turns with tons of jumps. In contrast, Supercross is an entirely man-made track, comprised almost exclusively of a wide array of jumps, and is typically held in an indoor stadium. Due to the size of outdoor tracks, motocross races typically include 40 racers, while supercross races usually have about 20.
Kart racing or karting is a variant of open-wheeler motor sport with simple, small 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 and more expensive ranks of motorsports.
Karts vary in speed and some (known as Superkarts) can reach speeds exceeding 160 mph (250 km/h). A Formula A kart, with a 100 cc 2 stroke engine and an overall weight including the driver of 150 kilograms, can accelerate from 0-60 mph in under 4.5 seconds, and has a top speed of 85 mph (140 km/h). It takes a little more than 3 seconds to go from 0 to 60 mph with a 125 cc shifter kart (6 gears), with a top speed of 115 mph (185 km/h) on long circuits.
Ellen says:I purchased two safety shoes for my two teenage sons Rj and Renz so that they can still wear shoes even on rainy days. The shoes look so elegant and make no difference from their school shoes. No one can notice that those are safety shoes.
