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.

ATV Motocross
Late in the 2003, Yamaha announced the YFZ450 for the 2004 model year. This ATV represented the first time a major manufacturer built a high-performance sport ATV suited for racing. While it wasn't as wide as many wanted for motocross and didn't have long-travel suspension, it featured a four-stroke engine very similar to the motocross dirt bikes Yamaha was putting out. The ATV also came stock with fully adjustable front suspension, the first time this was available on a stock ATV. After the Yamaha announcement, Honda announced it was going to bring the TRX450R to market in 2004. The tide was turning for the high-performance race ATV market.
The two-stroke spark-ignition engine's invention is generally credited to Joseph Day (and Frederick Cock for the transfer-port), whereas the two-stroke valved compression-ignition engine is attributed to Dugald Clark.
