Some interesting information about motocross:
Motocross - a type of motorcycling (racing) is a race to the special sports motorcycle carried out on cross-country in a closed circuit with natural (in the form of steep climbs, descents, turns, ditches, sand, etc.) and artificial (tables, ramps, bridges rut) obstacles.
Freestyle Motocross, a relatively new variation of supercross, does not involve racing and instead it concentrates on performing acrobatic stunts while jumping motocross bikes. The winner is chosen by a group of judges. The riders are scored on style, level of trick difficulty, best use of the course, and, frequently, crowd reactions.
Connection ride motorcycles over rough terrain at speeds was the impetus for the emergence of competition in cross-country motorcycling. One of the first publicly available on the cross-country competition has been so-called "race for the fox", conducted a military drill-ground near London in 1908. It was attended by 13 motorcyclists and 16 horse riders. The aim of motorcyclists was to prove that the new technology on the roads exceed the speed horses.
In the first motocross event was attended by riders on road bikes adapted for movement over rough terrain through their own efforts. Motorcycles facilitated by removing unnecessary for competition parts - headlights, brake lights, luggage compartment, passenger pegs, mirrors, modify the suspension, increased engine power.
Modern serial motocross motorcycles have a large suspension travel - 300 mm and more powerful engine and light frame. By type of workflow engine can be two-stroke or four-stroke. Do not have lighting equipment, mirrors, dashboard, side stops. More often than not have electric starter.
