What is Moto GP, Road Racing Chamionship Grand Prix?
The MotoGP is the pinnacle class of the world championship road racing that developed primarily in Europe after FIM (Federation Internationale de Motocyclisme) consolidated the regulations for motorcycle competition for the first time in 1949. In the past, the pinnacle class was the 500 cc class of the road race World Championships, but in 2002 the regulation was changed to create the MotoGP class in which 2-stroke machines of up to 500 cc and 4-stroke machines of up to 990 cc competed together. Then the regulation was changed again in 2004 to limit the MotoGP class to 4-stroke machines only. With the displacement limit now reduced to 800 cc, the fuel tank capacity reduced from 22L in 2006 to 21L, and the limited number of tires to be used for a race week (14 front tires and 17 rear tires) from the 2007 season, the 2006 season was the last for the 990 cc machines. The races are competed on paved circuits with a length of about four or five kilometers per lap. All the competitors start at the same time and compete to be the top finishers over the prescribed number of laps. The length of the final race is about 110 to 120 km and it is completed within about 40 minutes. During the race the competitors reach speeds of over 320 km/hr. Italian riders including Valentino Rossi and Giacomo Agostini have the best record, winning 18 titles in this premier class. Yamaha has a total of 12 titles, including ten GP500s and two MotoGPs.

Grand Prix motorcycle racing refers to the premier category of motorcycle road racing, currently divided into three distinct classes: 125 cc, 250 cc and MotoGP. Grand prix motorcycles are purpose-built racing machines that are neither available for general purchase nor can be legitimately ridden on public roads; this contrasts with the various production categories of racing, such as World Superbike, that feature modified versions of road-going motorcycles available to the public.
OverviewA World Championship for motorcycle racing was first organized by the Fédération Internationale de Motocyclisme (FIM) in 1949. The commercial rights are owned by Dorna Sports.
There have traditionally been several races at each event for various classes of motorcycles, based on engine size, and one class for sidecars. Classes for 50 cc, 80 cc, 125 cc, 250 cc, 350 cc, and 500 cc single seaters have existed over time, and 350 cc and 500 cc sidecars. Up through the 1950s and most of the 1960s, four-stroke engines dominated all classes. In the 1960s, two-stroke engines began to take root in the smaller classes. By the 1970s, two-strokes completely eclipsed the four-strokes. In 1979, Honda made an attempt to return the four-stroke to the top class with the NR500, but this project failed, and in 1983, even Honda was winning with a two-stroke 500. The 50 cc class was replaced by an 80 cc class, then the class was dropped entirely in the 1990s, after being dominated primarily by Spanish and Italian makes. The 350 cc class vanished in the 1980s. Sidecars were dropped from World Championship events in the 1990s (see superside), reducing the field to 125s, 250s, and 500s.
MotoGP, the premier class of GP motorcycle racing, has changed dramatically in recent years. From the mid-1970s until 2002 the top class of GP racing allowed 500 cc with a maximum of 4-cylinders, regardless of whether the engine was a two-stroke or four-stroke. Consequently, all machines were two-strokes, due to the greater power output for a given engine capacity. Some twin-cylinder two-stroke 500s were seen, but though they typically attained higher corner speed and could qualify well, they lacked the power of the four-cylinder machines. In 2002, rule changes where introduced to facilitate the phasing out of the two strokes, probably influenced by what was then seen as a lack of relevance large capacity two-stroke motorcycles had to the roadbikes the public could buy as, by this time, the last mass-produced 500 cc 2-stroke model had not been available to the public since some 15 years earlier. The rules permitted manufacturers to choose between running two-strokes engines (500 cc or less) or four-strokes (990 cc or less). Manufacturers were also permitted to employ their choice of engine configuration. Despite the significantly increased costs involved in running the new four-stroke machinery, given their extra 490 cc capacity advantage, the four strokes where soon able to dominate their two-stroke rivals. As a result, by 2003 no two-stroke machines remained in the MotoGP field. The 125 cc and 250 cc classes still consist exclusively of two-stroke machines. In 2007, the MotoGP class had its maximum engine displacement capacity reduced to 800 cc. In the smaller classes it is also intended to phase out two strokes from around 2010. The 125 and 250 classes eventually being replaced by 4 strokes of around 400 & 600 cc capacity.
The current racing calendar consists of 18 rounds in 16 different countries (Spain which hosts 3 rounds, Qatar, Turkey, China, France, Italy, Great Britain, Netherlands, Germany, Czech Republic, San Marino, Portugal, Japan, Australia and Malaysia). Exclusive to the MotoGP class, there is also a USA round at Mazda Raceway Laguna Seca in Monterey, California. The grid is composed of 3 columns (4 for the 125 cc class) and contains approximately 20 riders. Grid positions are decided in descending order of qualifying speed, the fastest on the 'pole' or first position. Races last approximately 45 minutes, each race a sprint from start to finish without pitting for fuel or tyres.
Tyre selection is critical, usually done by the individual rider based on bike 'feel' during practice, qualifying and the pre-race warm-up laps on the morning of the race, as well as the predicted weather. The typical compromise is between grip and longevity--the softer and 'grippier' the tyre, the more quickly it wears out; the harder and less grippy, the more likely the tyre is to last the entire race. Special 'Q' or qualifying tyres of extreme softness and grip are typically used by riders during grid qualifying sessions, but they last typically no longer than one or two laps, though they may deliver higher qualifying speed. For wet conditions, special tyres ('wets') with full treads are used, but they suffer extreme wear if the track dries out.
In 2005, a flag-to-flag rule for MotoGP was introduced. Previously, if a race started dry and rain appeared, riders or officials could red-flag (stop) the race and begin again on wet tyres. Now, if it begins to rain there is no red flag, though riders can pit to change their tyres at their discretion (and if a white flag is waved by officials).
When a rider crashes, track marshals wave a yellow flag, prohibiting passing in that area; one corner back, a stationary yellow flag is shown and passing in this area of the track is prohibited; if a fallen rider cannot be safely evacuated from the track, the race is red-flagged. Motorcycle crashes are usually one of two types: lowsides and highsides, though increased use of traction control has made highsides much less frequent.
According to one estimate, leasing a top-level motorcycle for a rider is about 3 to 3.5 million dollars.[1]
