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.

In contrast Supercross is an entirely man made track, comprising almost exclusively of a wide array of jumps and typically held in, READ ON...

This causes there to be a power stroke for every revolution of the crank, instead of every second revolution as in a four-stroke engine. For this reason, two-stroke engines provide high specific power, so they are valued for use in portable, lightweight applications. On the other hand large two stroke diesels have been in use in industry (i.e. locomotive engines) since the early twentieth century.
