New Class of MotoGP

New specifications for each age group are trained as FIM sees fit. At the beginning of the new MotoGP era in 2002, 500cc two-stroke or 990cc four-stroke motorcycles have specified in the race. The advantage of the enormous power of the largest displacement four-stroke engines during the two times to the two shots from the competition the following season only two-stroke bikes were racing to remove. In 2007, the maximum capacity was 800 cc without reducing the weight restrictions were reduced.
MotoGP-class motorcycles are not limited to a specific engine configuration. However, the number of cylinders provided in the motorcycle engine uses the minimum weight allowed more bottles more weight than a form of disability to win. This is because for a given capacity, a multi-cylinder engine is necessary in the situation more power. If comparable bore stroke ratios are used a multi-cylinder engine will have an area of the piston and a shorter stroke.

The increased piston area permits an increase in the total valve area so that more air and fuel are sucked in the engine, and the shorter stroke permits higher speeds on the same piston speed, allowing the engine pump more Air and fuel with the potential for more power to produce but with a higher rate. In 2004, motorcycles with any three, four and five-cylinder configurations. A six-cylinder engine was proposed by Blata, but did not reach the MotoGP grids. Currently, four-cylinder engines seem to be the best compromise between weight, performance and fuel economy that all competitors offer in the 2009 series use this solution as "V" or an online configuration.
In 2002, the FIM has become concerned about the progress of the development and construction which have led to higher speeds at the race track. been introduced to improve safety, regulatory changes in terms of weight, the quantity of remaining fuel and engine capacity. The amended rules reduced engine capacity from 800cc to 990cc and limit the amount of fuel for the race distance from 26 liters to 21 liters in 2004 for the years 2007 and beyond. Additionally, the minimum weight of 4-cylinder bike by all the participating teams has increased use of 3 kg.
The highest speed for a MotoGP bike 349.288kph (217,037 hours miles), followed by Dani Pedrosa set Repsol Honda RC212V riding a 800cc for a practice session at the 2009 Motorcycle Grand Prix of Italy.
On 11 December 2009, the Grand Prix Commission announced that the MotoGP class was the 1000 cc engine from the 2012 season limit. Maximum stay will be limited to 1,000 cc, is would a maximum of four and maximum cylinder bore of 81 mm.Carmelo capped Ezpeleta, CEO of Dorna Sports, said the proposed changes have been positively received by the teams.
