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.

A major drawback of this is that four-strokes produce a deeper sound compared to two-stroke, which has led to a sharp rise in sound complaints across the world. To make the four-stroke competitive the world sanctioning body amended the displacement categories so that a 125cc two-stroke would compete against a 250cc four-stroke, and a 250cc two-stroke would compete against a 450cc four-stroke. By this point, the 500cc class had been dying out due to their immense power allowed fewer riders with enough talent to ride them at their limits.
No standard definition of what constitutes a pit-bike by any major governing body exits, but the normal requirement is a 14" front wheel, and a 12" rear (or smaller). None of the big 5 manufactures (Honda, Yamaha, Suzuki, Kawasaki, and KTM ) currently offer "race ready" pit-bikes, however some other companies are beginning to sell bikes designed solely for this purpose.
