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.

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 As development progressed the power output of these bikes superseded their two-stroke equivalents, further sealing their fate.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.
The yellow flag
The solid yellow flag, or caution flag, universally requires drivers to slow down due to a hazard on the track. However, the procedures for displaying the yellow flag vary for different racing styles and sanctioning bodies.
In Formula One racing, a yellow flag displayed at the starter's stand or a marshal station indicates that there is a hazard downstream of the station. The manner of display depends on the location of the hazard:
- A single stationary flag denotes a hazard off the course
- A single waved flag denotes a hazard on the racing surface itself
- A double waved flag denotes a hazard that wholly or partly blocks the racing surface. This informs the driver to prepare to stop, if necessary.
