The classes that exist when it is 50cc, 125cc, 250cc, 350cc, and 500cc single seater for the motor, as well as 350cc and 500cc sidecars for motorcycles. Entering the 1950's and throughout the 1960s, 4-stroke motorcycle engine dominates the entire class. In the late 1960s, the motorcycle-engined 2 not begin to master the small classes.
In the 1970's 2-stroke motorcycle engine really get rid of 4 stroke engines. In 1979, Honda attempt to restore the engine 4 stroke by lowering the top class motor NR500, but this project failed, and in 1983, even Honda was winning with his 2-stroke 500cc motor.
In 1983, 350cc class finally abolished. 50cc Class 80cc later replaced by a classroom in 1984, but the class is often dominated by riders from Spain and Italy was finally abolished in 1990. Class sidecars are also excluded from the world championships in the 1990's, leaving the 125cc, 250cc, and 500cc classes.
GP 500, the premier class of Grand Prix motor racing, has changed dramatically in 2002. From the mid-1970s until 2001 the top class of GP racing and is bounded 4-cylinder engine capacity of 500cc, both types of engines 2 stroke or 4 stroke. As a result, are able to survive the 2-stroke engine, which incidentally generate power and greater acceleration.
In 2002 to 2006 for the first time allowed manufacturers to increase the total capacity of special machines for a maximum of 4 stroke engine 990cc, 800cc and turned into the 2007 season. Manufacturers are also given the freedom to choose the number of cylinders that are used between three to six with a certain weight limit. With the motor permissibility cc 4 stroke air-large, the GP 500 class renamed to MotoGP. After 2003 no longer exists 2-stroke engine that fell in the MotoGP class. For 125cc and 250cc classes in particular are still using the 2-stroke engine.
Racing for the MotoGP class is currently held as many as 17 series in 15 different countries (Spain held a three race series). Regular races held every weekend with several stages. Held Friday free practice and first official practice, then on Saturday held the second official practice and QTT, in which the drivers try to make the record the best time to determine their starting position.
MotoGp History
Motor racing contest contest has been known since 1900. At that time managed by the FICM (Federation Internationale des Clubs Motocyclistes) referred to as his great-grandfather FIM today. Competition conducted dieropa dominant technological developments, especially because the motor has not so global in those days. FICM formed in 1938 announced a dieropa motor racing championship. But the plan did not go smoothly due to collide with the outbreak of world war two. After the war new motor racing championship back to life, slowly but surely competition has begun venturing into the international level. MotoGP championship finally officially organized in 1949, divided by four main classes, namely classes 500cc, 350cc, 250cc and 125cc.
Logged mat first MotoGP world championship was won by Leslie Graham joined the team AJS Porcupine (500cc), Freddie Frith on Velocette team (350cc), Bruno Ruffo on the Moto Guzzi team (250cc) and Nello Pagani at the Mondial team (125cc). That decade the Italian manufacturing, Mondial and Moto Guzzi and MV Agusta Gilera together dominate the MotoGP race. The peak is about the 1950 MV Agusta not half-hearted they swept four different classes in three consecutive seasons (1958-1960).
And for 17 years of dominance in the 500cc never been solved as a manufacturer who could win the class of kings were continually since the year 1958 to 1974 until the crown was slowly eroded by Japanese manufacturers began to exist after World War II. Japanese motorcycles began to boom in 1960. Through the three brands at that time Honda, Suzuki and Yamaha manufacturer terrorized Italy in all 125cc, 250cc and 500cc (1960).
For the rider, the end of 1960 comes the reply of a name is quite prominent because of his achievements is Giacomo Agostini. year 1960 was a historic year for Giacomo Agostini. That year he began to carve his name in the history of MotoGP.
Giacomo Agostini is the most successful rider of all time (only Valentino Rossi, who approached his record). Golden age when he rode the MV-Agusta (1968). Because of the high cost of forcing the Japanese manufacturer withdrew join MotoGP and Yamaha only remaining at the time. Until the early 1970s their new re-join. At that period the world title contested by European manufacturers (Bultaco, Kreidler, Morbidelli, and MV Agusta) American (Harley Davidson) and Japan (Yamaha, Honda, Kawasaki).
The dominance of MV Agusta was a little disturbed by the motors from Japan. After nearly 12thn break back Honda MotoGP arena (mid 1970) and in around 1983 they changed the philosophy of the engine switch engine 4tak 2tak (V3 500) is more famous for its NS500. Honda NS500 successfully deliver a world champion for the first time through the joint dimotogp rider Freddie Spencer.
Year 1980-1990 was a year when the Japanese manufacturer is dominating. In the years that the quality of motor racing entered the stage of modern technology with the level of competition is very tight. The fight between the yamaha brand, Honda and Suzuki produce classic duel-duel that very interesting. Logged Eddie Lawson, Randy Mamola, Freddie Spencer, Wayne Rainey and Kevin Schwantz is a brilliant rider-rider at that time. Generation of 500cc and above in 1990 was dominated by Michael Dohan the NSR 500. Doohan managed to carve a record five-time world champion until an injury forced him to retire early from the arena of MotoGP (1999).
After the Italian rider fading echoes of post Agostini in 1997 appears Valentino Rossi . Rossi is a world champion rider 500cc 2tak cover in the series before it was changed to 4tak 990cc engine. On his journey level 990cc engine is too tight so that the FIM issuing new regulations to cut the rate by safety objectives (based on the experience of death Daijaro Kato on April 2003).
become effective in 2007 MotoGP engine do downgrade again to 800cc until now. Analysis of FIM officials were wrong, because the 800cc machines were not more quietly than 990 machine (technological advances), especially in the strong devour the corner so that the discourse of race being deliberated for the return of premium-class motor racing is returning to 990cc in 2012.
Motor Grand Prix Organizations
FIM (Federation Internationale de Motocyclisme) is the highest body in the world to take care of things about motorcycles. FIM standing in 1904 was not only deal with motor racing, but also became superintendent of production motorcycles are sold en masse, especially about the safety and feasibility. In motor racing events, the FIM is the agency in charge of and responsible regarding the regulatory and technical aspects of the race, also on the status, extent, and the criterion of a motor racing championship.
Dorna is MotoGP race organizers organization, or in other words is the promoter Dorna MotoGP championship. Dorna is responsible for the quality of the event and also take care of event sponsors.
IRTA (International Road Racing Team Association), a member of this organization consists of teams who follow the MotoGP race. This organization serves to channel the aspirations of the team and the drivers are incorporated in it. With this organization riders can provide input and determine the rights and interests, including contract value, safety and feasibility of the circuit.
MSMA (Motorcycle Sports Manufacturer Association) is an organization comprised of the MotoGP motorcycle manufacturers who follow the MotoGP championship, such as Honda, Yamaha, Ducati, Suzuki, Kawasaki, and other manufacturers. The function of this organization, among others, to decide the technical regulations regarding the regulation of the motor along with other organizations who are members of the commission Grand Prix.
MotoGp Specification
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 of MotoGP in 2002, motorcycle-engined 2-stroke 500 cc and 990 cc 4 stroke allowed for use in the race. Virulence power of the motor 4 stroke engine that powered 2 stroke motors outperform rid of all 2-stroke engine of competition, and the subsequent racing seasons there is no more 2 stroke motors are used.
The 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 overdrive transmissions are permitted) according to observers Honda MotoGP is very profitable. Honda uses a five-cylinder engine, and only need to reduce one cylinder to fix their machines to suit the new regulations, while other manufacturers have to redesign all of their machines. Restricted to 800 cc also caused controversy that seems current motors are used in a 1000 cc superbike championship to be the fastest in the motor racing circuits around the world.
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 increase. 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.
These motors are used in motor Grandprix made not only for racing only, but also as an opportunity to showcase the power and technological advancement among manufacturers. As a result the entire MotoGP machines are made by using materials that are very expensive and as light as titanium, and carbon-fiber-reinforced plastic. These motors are also using 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.
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 horsepower (179 kW), through the contact points of two tires and the asphalt surface of a circuit with a width of only about a human arm. As a comparison of the F1 car produces over 950 hp (700 kW) but with four tires, so having a point of contact with the asphalt surface ten times wider than a MotoGP bike.
Recent regulatory changes
In 2002, the 500 cc class was replaced into the MotoGP, the motor capacity of 990 cc.
In 2005, a new rule for MotoGP has enacted the flag-to-flag. Previously, if a race starts with a start in dry circuit conditions and the rain falls, the leading rider can lift a hand to stop the race, so also with the officials waving a red flag to stop the race, then the race began again using wet tires. Now if the rain falls during the race no longer a red flag, the drivers directly to the pits to change tires at the discretion of the team.
In 2007, the MotoGP class derived engine capacity, to 800 cc.
In 2010, imposed restrictions on the MotoGP class machines 6 engine for a season.
In 2010, the 250 cc class was replaced by a classroom moto2 with prototype engine 4 stroke 600 cc.
In 2012, the MotoGP class increased engine capacity, to 1,000 cc.
