Grand Prix motor refers to the top class of motorcycle racing, currently divided into three classes of machine different: 125cc, 250cc and MotoGP (over 990cc). Motors used in MotoGP is made specifically for motor racing, and not sold to the public (street version of the motor for 125 and 250cc classes available). This contrasts with the various production categories of racing, such as World Superbike, that feature modified versions of motorcycles available for general.
History
Road Racing World Championship was first organized by the Federation Internationale de Motocyclisme (FIM) in 1949. At that traditionally have been held several races at each event for different classes of motors, based on engine capacity, and classes for sidecars (Motor bersespan). Existing classes when it is 50cc, 125cc, 250cc, 350cc, and 500cc for single-seater racing motorcycles, and 350cc and 500cc sidecars for motorcycles. Entering the 1950s and throughout the 1960s, motorcycle engines, four did not dominate the entire class. In the late 1960s, the motor engined two did not begin to master the small classes. In the 1970s, motorcycle engines, two did not really get rid of 4 stroke engines. In 1979, Honda tried to restore the engine 4 stroke the top class by lowering the motor NR500, but this project failed, and in 1983 Honda even winning with a 500cc bike not his second. In 1983, 350cc class finally abolished. 50cc class was replaced by the year 1984 80cC class, but class often dominated by the Spaniard and the Italian was finally abolished in 1990.
Class sidecars are also excluded from the world championships in the 1990s, leaving the 125cc, 250cc, and 500cc classes.
GP 500, the premier class of Grand Prix motor racing, has changed dramatically in recent years 2002. From the mid-1970s until 2001 the top class of GP racing limited four-cylinder and engine capacity of 500cc, both types of engines 4 stroke or 2 stroke. As a result, which can survive engine is 2-strokes, produces power and greater acceleration. In 2002 for the first time, manufacturers are allowed to enlarge the total capacity of a special machine for 4 stroke engine to a maximum of 990cc, and gave freedom to choose the number of cylinders used between three to six with a certain weight limit. With the motor bolehkannya 4 990cc no, the 500 GP class renamed to MotoGP. After the year 2003 does not exist anymore two machines that do not fall in the MotoGP class. For 125cc and 250cc classes in particular still using two machines do not.
Race for the MotoGP class is currently held as many as 17 series in 15 different countries (Spain held the third race weekend). Used in the title race every weekend with several stages.
Friday free practice at the title and the first official practice, and then carried out practice Saturday both official and QTT, where the drivers trying to make the best time to record determine their starting position. Own race was held on Sunday, although there was a series of Saturday is held in the Netherlands and Qatar. Grid (row starting position) consists of three drivers per line and usually every racing series was followed by about 20 drivers.
