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.

Major Motocross Machines
The most common distinction between motocross machines is whether they have two-stroke or four-stroke engines. Originally all bikes were four-stroke (in the Pre-65 era), but as the two-stroke engine improved they became more popular with their domination of the sport in the 1970s, 80s and 90s. The two-stroke engine produced more power than a four-stroke engine of the same capacity (cc), however fuel had to be mixed with oil. Four-stroke continued to be raced in specialist classes throughout this period, partially in the MX3.
Speedway racing takes place on a flat oval track usually consisting of dirt or loosely packed shale, the official definition being "a track with a top surface in granite, shale, brick granules or similar unbound material rolled in on the base ground".[1] Competitors use this surface to slide their machines sideways (powersliding or broadsiding) into the bends using the rear wheel to scrub-off speed while still providing the drive to power the bike forward and around the bend.
