At the beginning of a new era of MotoGP in 2002, 2-stroke engine motorcycles 500cc and 990cc 4 stroke allowed to use in the race. Awesomeness power of 4-stroke motorcycle engine that surpass 2-stroke engine motorcycles aside all 2-stroke engine of competition.
In 2007, the FIM will impose new regulations that MotoGP bikes will be limited to 800cc 4 stroke. The reason given on the reduction of engine cylinder capacity is to increase driver safety, given the power and speed of the resulting peak MotoGP machines has increased dramatically since 2002. The current MotoGP speed record is 347.4 km / h, set by Loris Capirossi with Ducati at the Circuit de Catalunya, Barcelona in 2004. As a comparison, the current F1 speed record is 369.9 km / h which is printed by Antonio Pizonia with BMW, at Monza in 2004.
The decision to limit the choice of engine capacity to 800cc (than with other methods of power restrictions, such as a reduction in the amount of overdrive transmission permitted) according to observers very profitable Honda MotoGP. Honda uses a five-cylinder engine, and only need to reduce the cylinder to fix their machine to fit the new regulations, while other manufacturers have to redesign their entire machine.
Motor for the MotoGP class is allowed to use the machine with the number of cylinders between three to six cylinders, and there are variations in the weight restrictions depending on the number of cylinders used. This is due to an engine with more cylinders, the power generated is also greater, and increased weight limits. In 2006 machines used in MotoGP are four and five-cylinder engine. Honda uses a five-cylinder, while Yamaha, Ducati, Kawasaki, and Suzuki uses a four-cylinder.

Motors that are used in the motor Grandprix made not just to race, but also as an opportunity to showcase the strength and technological advances between manufacturers. As a result the entire MotoGP machines are made by using very expensive materials and light as titanium, and carbon-fiber-reinforced plastic. These motors are also using technology that was not available for public consumption, for example, is a sophisticated electronic device including telemetry, engine management systems, traction control, carbon disc brakes, and a modern engine technology adopted from the F1 car engine technology.
If the motors are used in the MotoGP class only competed at the world championship level, the motors are used in the 125cc and 250cc classes are relatively more affordable. The price of a 125cc or less the same as a car. These motors are often used in national motor racing championships around the world.
One of the major challenges facing the MotoGP riders and engineers MotoGP bike is how to deliver exceptional engine - more than 240 hp (179 kW), through the point of contact of two tires and asphalt surface with a width of only a circuit around a human arm. For comparison F1 car produces more than 950 hp (700 kW) but with four tires, so it has a point of contact with the asphalt surface ten times wider than a MotoGP bike.
