Dirt Bike Motocross: History & Fun Facts

From British Scrambles to Motocross

Off-road motorcycle racing traces back to 1920s England, where riders called their muddy cross-country races scrambles, chasing each other over hills, ditches, and open fields on machines barely modified from street bikes. The French later renamed the sport motocross, blending the word motorcycle with cross-country, and the name stuck worldwide as the sport spread across Europe and into the United States.

Early scramble bikes still carried heavy road-going frames and skinny tires, nothing like the purpose-built machines racers ride today, so much of motocross history is really a story about engineers stripping weight and adding suspension travel year after year.

Why the Frame Stays Exposed

Unlike a street motorcycle, a motocross dirt bike carries no body fairing covering the frame, since bodywork would only trap mud, add weight, and crack the first time the bike landed hard off a jump. That open tubular frame drawn on this sheet lets riders and mechanics see and reach every part of the machine quickly between motos.

A slim seat replaces the wide cushioned saddle found on a street bike, letting a rider shift body weight forward and back easily while standing on the pegs through rough terrain.

Suspension Built for Big Jumps

Long front fork tubes and a rear shock, both clearly visible on this coloring page, give a motocross bike far more suspension travel than any street motorcycle, often close to a foot of movement at each wheel. That extra travel absorbs the hard landings racers take off jumps and rutted whoops sections without bottoming out the frame.

A tall front fender, mounted high above the front tire rather than tucked close like a street bike, keeps thrown mud and dirt clods from blocking the rider's view during a race.

Knobby Tires That Grip Loose Dirt

The deep block-shaped tread called knobby tread lets a motocross tire dig into loose dirt, sand, and mud the way a smooth street tire never could, biting into soft ground for traction under hard acceleration and braking. Spoked wheels stayed standard on dirt bikes long after street motorcycles switched to solid alloy wheels, since spokes flex slightly and survive rough landings better than a rigid rim.

Two-stroke engines dominated motocross racing for decades because of their light weight and instant power delivery, though modern four-stroke engines now share the starting gate at most professional AMA Motocross events.

The Number Plate on the Front

A small number plate mounted on the front of the bike, drawn just above the fender in this scene, lets race officials and spectators identify a rider from a distance during a moto, a tradition carried over from the earliest organized scrambles races. Side panels near the seat often carry a second number for the same reason, since a rider can pass a dozen others in a single lap of a motocross track.

Skid plates bolted beneath the engine protect the crankcase from rocks and roots kicked up on rough trails, one more part borrowed from off-road racing that keeps a dirt bike running after a hard day on the track.
