 currently divided into three distinct classes: 125cc, Moto2 and MotoGP. The 125cc class uses a two-stroke engine while Moto2 and MotoGP use four-stroke engines. In 2010 the 250cc two-stroke was replaced by the new Moto2 600cc four-stroke class. Grand Prix motorcycles are purpose-built racing machines that are neither available for purchase by the general public nor can be ridden legally on public roads.

. Teams are represented by the International Road Racing Teams Association (IRTA) and manufacturers by the Motorcycle Sport Manufacturers Association (MSMA). Rules and changes to regulations are decided between the four entities, with Dorna casting a tie-breaking vote. In cases of technical modifications, the MSMA can unilaterally enact or veto changes by unanimous vote among its members. These 4 entities compose the Grand Prix Commission.

There have traditionally been several races at each event for various classes of motorcycles, based on engine size

, 80cc, 125cc, 250cc, 350cc, and 500cc solo machines have existed over time, and 350cc and 500cc sidecars. Up through the 1950s and most of the 1960s, four-stroke engines dominated all classes. In part this was due to rules which allowed a multiplicity of cylinders (thus smaller pistons, thus higher revs) and a multiplicity of gears (thus narrower power bands, thus higher states of tune). In the 1960s, two-stroke engines began to take root in the smaller classes. In 1969 the FIM, citing high development costs for non-works teams, brought in new rules restricting all classes to six gears and most to two cylinders (four cylinders in the case of the 350cc and 500cc classes). This led to a mass walk-out of the sport by the previously highly successful Honda

 on its return to GP racing 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 50cc class was replaced by an 80cc class, then the class was dropped entirely in the 1990s, after being dominated primarily by Spanish and Italian makes. The 350cc 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 through 2001, the top class of GP racing allowed 500cc 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 two- and three-cylinder two-stroke 500s were seen, but though they had a minimum-weight advantage under the rules, typically attained higher corner speed and could qualify well, they lacked the power of the four-cylinder

 machines. In 2002, rule changes were introduced to facilitate the phasing out of the two strokes, probably influenced by what was then seen as a lack of relevance: the last mass-produced 500cc 2-stroke model had not been available to the public for some 15 years. The rules permitted manufacturers to choose between running two-strokes engines (500cc or less) or four-strokes (990cc 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 490cc capacity advantage, the four-strokes were soon able to dominate their two-stroke rivals. As a result, by 2003 no two-stroke machines remained in the MotoGP field. The 125cc and 250cc classes still consist exclusively of two-stroke machines. In 2007, the MotoGP class had its maximum engine displacement capacity reduced to 800cc for a minimum of 5 years. For the 2012 season the capacity will be increased again to 1000cc.
The 2008 racing calendar consisted of 18 rounds in 16 different countries (Spain which hosted 3 rounds, Qatar, Turkey, China, France, Italy, Great Britain, the Netherlands, Germany, Czech Republic, San Marino, Portugal, Japan, Australia and Malaysia). Exclusive to the MotoGP class, there was also a USA round at Mazda Raceway Laguna Seca

 for the first time on a newly prepared track, and observers noted that the Speedway had hosted motorcycle racing before cars raced there. All three classes were scheduled to race but severe wind and rain prevented the 250cc class from racing. MotoGP racing at Indianapolis is counterclockwise, with a new Snake Pit complex past the start-finish line before heading down the Turn 1 short chute and into the infield section.

The grid is composed of three columns (four for the 125cc and 250cc classes) and contains approximately 20 riders. Grid positions are decided in descending order of qualifying speed, the fastest on the 'pole'

The term "pole position", as used in motorsports, comes from the horse racing term where the number one starter starts on the inside next to the inside pole.

 or first position. Races last approximately 45 minutes, each race a sprint from start to finish without pitting for fuel or tyres.

In 2005, a flag-to-flag rule for MotoGP was introduced. Previously, if a race started dry and rain fell, riders or officials could red-flag (stop) the race and either restart or resume on 'wet' tyres. Now, if rain falls a white flag is shown, indicating that riders can pit to swap the motorcycle on which they started the race for an identical one, as long as the tyres are different (that is, intermediates instead of wets, or slicks instead of wets)http://world.honda.com/WGP/2005/02portugal/race/. Besides different tyres, the wet-weather bikes have steel brake rotors and different brake pads

 instead of the carbon discs and pads used on the 'dry' bikes. This is because the carbon brakes need to be very hot to function properly, and the water cools them too much. The suspension is also 'softened' up somewhat for the wet weather.

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 evacuated safely from the track, the race is red-flagged. Motorcycle crashes are usually one of two types: lowsides and the more dangerous 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 costs about 3 to 3.5 million dollars for a racing season.

As a result of the 2008-2009 financial crisis, MotoGP is undergoing changes in an effort to cut costs. Among them are reducing Friday practice sessions; banning active suspension, launch control and ceramic composite brakes; extending the lifespan of engines; and reducing testing sessions.

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—softer compound tyres have more traction, but wear out more quickly; harder compound tyres have less traction, but are more likely to last the entire race. Conserving rubber throughout a race is a specific talent winning riders acquire. Special 'Q' or qualifying tyres of extreme softness and grip were typically used during grid-qualifying sessions until their use was discontinued at the end of the 2008 season, but they lasted typically no longer than one or two laps, though they could deliver higher qualifying speeds. In wet conditions, special tyres ('wets') with full treads are used, but they suffer extreme wear if the track dries out.

In 2007 new MotoGP regulations limited the number of tyres any rider could use over the practice and qualifying period, and the race itself, to a maximum of 31 tyres (14 fronts and 17 rears) per rider. This introduced a problem of tyre choice vs. weather (among other factors) that challenges riders and teams to optimize their performance on race day. This factor was greeted with varying degrees of enthusiasm by participants. Bridgestone

, winner of the 2001-2005 and later the 2008 and 2009 titles. In an effort to beat Valentino's amazing consecutive victories on the 500-cc two-strokes and then the 990-cc four-stroke machines, other companies signed younger riders on newly designed 800-cc machines.

. The use of any device on the motorcycle to artificially decrease the temperature of the fuel below ambient temperature is forbidden. No motorcycle may include such a device.' This stops an artificial "boost" gained from increasing fuel density by cooling it.

s. From 2005 onwards, all riders in the 125cc class could not be older than 28 years or 25 years for new contracted riders participating for the first time and wild-cards.

Moto3 class

The 125cc class will be replaced in 2012 by the Moto3 class. This class will be restricted to single cylinder 250cc 4-stroke engines with a maximum bore of 81 mm.http://www.crash.net/motogp/news/162431/1/official_moto3_to_replace_125cc.html

However, there will be no chassis limitations. From 2010 onwards, only 600 cc four-stroke Moto2 machines are allowed.

MotoGP class

MotoGP is the 800cc class. The FIM
Fédération Internationale de Motocyclisme
The Fédération Internationale de Motocyclisme is the governing body of motorcycle racing. It represents 103 national motorcycle federations that are divided into six regional continental unions....

 has altered the specification for the class at several points in its history. At the beginning of the new MotoGP era in 2002, 500cc two-stroke or 990cc four-stroke bikes were specified to race. The enormous power advantage of the larger displacement four-stroke engine over the two-stroke eliminated all two-strokes from competition; the following season no two-stroke bikes were racing. In 2007 the maximum engine capacity was reduced to 800cc without reducing the existing weight restrictions.

MotoGP-class motorcycles are not restricted to any specific engine configuration. However, the number of cylinders employed in the engine determines the motorcycle's permitted minimum weight; the weight of the extra cylinders acts as a form of handicap
Handicapping
Handicapping, in sport and games, is the practice of assigning advantage through scoring compensation or other advantage given to different contestants to equalize the chances of winning. The word also applies to the various methods by which the advantage is calculated...

. This is necessary because, for a given capacity, an engine with more cylinders is capable of producing more power. If comparable bore to stroke ratios are employed, an engine with more cylinders will have a greater piston area and a shorter stroke. The increased piston area permits an increase in the total valve area, allowing more air and fuel to be drawn into the engine, and the shorter stroke permits higher revs at the same piston speed, allowing the engine to pump still more air and fuel with the potential to produce more power, but with more fuel consumption too. In 2004 motorcycles were entered with three-, four-and five-cylinder configurations. A six-cylinder engine was proposed by Blata, but it did not reach the MotoGP grids. Presently four cylinder engines appear to offer the best compromise between weight, power, and fuel consumption as all competitors in the 2009 series use this solution in either 'V' or in-line configuration.

In 2002, the FIM became concerned at the advances in design and engineering that resulted in higher speeds around the race track
Race track
A race track is a purpose-built facility for racing of animals , automobiles, motorcycles or athletes. A race track may also feature grandstands or concourses. Some motorsport tracks are called speedways.A racetrack is a permanent facility or building...

. For purposes of increasing safety, regulation changes related to weight, amount of available fuel and engine capacity were introduced. The amended rules reduced engine capacity to 800cc from 990cc and restricted the amount of available fuel for race distance from 26 litres in year 2004 to 21 litres in year 2007 and onwards. In addition, the minimum weight of 4 cylinder bike used by all participating teams was increased by 3 kg.

The highest speed for a MotoGP motorcycle in 125cc category is 249.76 km/h (155.193 mph) by Valentino Rossi in 1996 for Aprilia and the top speed in the history of MotoGP is 349.288 km/h (217.037 mph), set by Dani Pedrosa riding a Repsol Honda RC212V 800cc during Free Practice 1 at the 2009 Italian motorcycle Grand Prix

On December 11, 2009, the Grand Prix Commission announced that the MotoGP class would switch to the 1000 cc motor limit starting in the 2012 season. Maximum displacement will be limited to 1000 cc, maximum cylinders would be limited to 4, and maximum bore would be capped at 81 mm. Carmelo Ezpeleta, the CEO of Dorna Sports
