Motocross bikes

Originally motocross competitions participated in the normal road bikes, adapted by racing teams for use on rough terrain and light off-road. For this bike facilitated by removing unnecessary parts in the competition - lights, brake lights, luggage carriers, passenger footrests and seats, mirrors. Besides being finalized suspension and if necessary, increase capacity motorcycle.

in popularizing motorsport crossover, began to appear, and serial motocross bikes. These motorcycles have evolved in a constructive manner. So wide wheel, designed to increase the lever rotation decreased. The fork and the pendulum, on the contrary, - increased. Exhaust pipes, usually at the bottom, were raised to prevent damage if dropped.

The development of technology has led to the relief of engines by increasing their capacity. This would eliminate the heavy four-stroke engines in favor of lightweight high-revving structurally simple 2-stroke. Now used only single-cylinder engines.

To reduce weight and simplify the construction of an electric starter was removed, instead, on motorcycles krosovyh usually a kick starter. Lack of electricity consuming devices allowed to refuse and battery.

In the design of the bike, and changed tires. Began to make a special off-road tires, radically improve handling motocross bike.

So, after innovations 80s, there was a modern motocross bike scheme:

• seat is the fuel tank, allowing the pilot to move freely motorcycle
• disc brakes, in the mid-90s to completely replace old and inefficient heavy drum brakes
• greatly changed compared with other classes of motorcycle suspension, it was progressive with monoshock, which significantly increase the stroke of the pendulum, to reduce weight and to adapt the shock absorber to the extreme racing modes of operation
• water cooling instead of air

motocross bike was associated with improved handling, reduced weight and dynamics.

So there was an inverted front fork, which allowed for higher speeds greatly improve the front suspension.

With the advent of new materials and alloys have been further improved driving dynamics and moschnoti motorcycles.

But in the 90's were bitter environmental requirements and standards, which forced to go back to 4-stroke engines. However, the new engines by using modern technologies have sufficient reliability and light weight.

Now the modern commercial motocross bikes have a large suspension travel (300 mm or more) for preodaleniya most difficult sections on the road, a powerful but easy to drive and easy robust frame. Now represented as a 2-stroke and 4-stroke engines. Motocross bikes (Unlike other motorcycle enduro class) do not have the lighting equipment, mirrors, instrument panels and side supports. Many models have electric start and (in 2011 introduced a range of KTM motocross bikes with electric start).

motocross bike can not be operated on the roads of general use, as they do not have the proper lighting equipment, instrument panels, mirrors. These bikes are not certified, have the vehicle registration and therefore not recorded in the traffic police authorities. To manage such bikes do not need a driver's license because they are sporting equipment.
