Any regulations regarding each race class is formed by the FIM as the organization authorized to do so. FIM forms and issuing new regulations are deemed in accordance with the development of the race. At the beginning of a new era in the 2002 MotoGP, motorcycle engines, 2 stroke 500 cc and 990 cc 4 stroke allowed for use in the race. Magnitude of power of a 4 stroke motorcycle engines, motorcycle engines, 2 stroke ahead of getting rid of all 2-stroke engine of competition, and the next racing season there is no more 2 stroke motors are used.
In 2007, FIM will impose new regulations that the MotoGP bikes will be limited to 4-stroke 800 cc. The reason given from the engine cylinder capacity reduction is to improve driver safety, considering the power and speed of the resulting peak MotoGP machines has increased dramatically since 2002. Current MotoGP speed record is 347.4 km / h which is printed by Loris Capirossi on a Ducati motorcycle circuit Catalunya, Barcelona in 2004. For comparison the current F1 speed record is 369.9 km / h which is printed by Antonio Pizonia with BMW cars, the Monza circuit in 2004.
Decision to limit the choice of a 800 cc engine capacity (rather than with other methods of power restrictions, such as reducing the amount of gear transmissions are permitted) according to observers Honda MotoGP is very profitable. Honda uses a five-cylinder engine, and only need to reduce the cylinder to fix their machines to fit the new regulations, while other manufacturers have to redesign all of their machines. Limitation to 800 cc also caused controversy that currently seems to motors used in the 1000 cc superbike championship to be the fastest in the motor racing circuits around the world.
Machines used in the 125 cc class is limited to one cylinder and with a minimum weight of 80 kilograms, while the 250 cc class is limited to two cylinders with a minimum weight of 100 pounds.
Motor-bike for the MotoGP class are allowed to use the machine with the number of cylinders between three and six-cylinder, and there are variations in the weight restrictions depending on the number of cylinders used. This is due to an engine with more cylinders, power output is also greater, and the weight limit increases. In 2006, the machines used in MotoGP are four-and five-cylinder engine. Honda uses a five-cylinder, while Yamaha, Ducati, Kawasaki, and Suzuki use a four cylinder.
Motors used in the motor Grandprix made not only to race, but also as a venue for a show of force between the manufacturer and technological advances. As a result the entire MotoGP machines are made using materials that are very expensive and as light as titanium, and carbon-fiber-reinforced plastic. These motors also use a technology that is not available for public consumption, for example, is a sophisticated electronic devices, including telemetry, engine management systems, traction control, carbon disk brakes, and engine technologies are adopted from the modern F1 car engine technology.
If the motors are used in the MotoGP class only competed at world championship level, the motors used in the class 125 cc and 250 cc are relatively more affordable. The price of a motorcycle of 125 cc or less the same with a car. These motors are often used in national motor racing championship in the world.
One of the major challenges facing some of the drivers and engineers MotoGP MotoGP bike is how to deliver exceptional engine power - more than 240 hp (179 kW), through the contact point of two tires and the asphalt surface of the circuit with a width of only about a human arm. As a comparison of a F1 car generates over 950 hp (700 kW) but with four tires, so have a point of contact with the asphalt surface ten times wider than a MotoGP bike.
