motocross Introduction
Motocross, also abbreviated as MX, is the combination from the words ¡°Motorcycle¡± and ¡°Cross Country¡±.
The motorcycles used in the motocross races are lightweight and powered by two stroke or four stroke engines. The engines are highly tuned with absorbent suspension designed to deal with the shock of heavy landings, and short gearing designed for swift acceleration rather than high top speed.
Many MX racers begin when they're young, and grow up in the sport as a family activity. But it is not the rule and if you like, you can start at any age, especially for enthusiastic trail rider, or those who love riding dirt bikes or racing when they are young.
Motorcross racing is one of the most appealing forms of motorsport, with riders performing seemingly death defying leaps, turns visibly at the edge of traction, and the effort of riders clearly visible as the move their bodies around their motorcycles to balance the bikes for maximum speed.
Capitalising on this appeal, a variant called "Supercross" has evolved, held on tighter tracks in sports stadiums with more, even higher jumps.

The first stadium motocross event was held in 1972 at the Los Angeles Coliseum. In 1975, a 125cc world championship was introduced. European riders continued to dominate motocross throughout the 1970s but, by the 1980s, American riders had caught up and began winning international competitions.

Yamaha introduced the first "modern" four-stroke with the YZ400F, which was soon succeeded by the YZ426F and then by the "standard" 450cc machine. Other manufacturers soon followed suit, downplaying their 250cc two-stroke bikes. As development progressed the power output of these bikes superseded their two-stroke equivalents, further sealing their fate. The four-stroke revolution continued with a wave of 250cc four-stroke machines to compete against the 125cc two-strokes.
