In December 2009, the FIM’s Grand Prix Commission previously approved the switch to 1,000cc engines with a limit of four cylinders and a maximum bore of 81 mm. The new regulations, defined during a meeting Feb. 17, further defined the technical regulations for the 2012 MotoGP season.
Teams continuing to use 800cc motorcycles in 2012 must meet a minimum weight of 150 kg (330.7 lbs.) while teams racing motorcycles with engine displacements higher than 800cc must meet a minimum weight of 153 kg (337.3 lbs.). Fuel tanks will also be capped at 21 liters (5.55 gallons).
Privateer teams, referred to in the regulations as “Claiming Rule Teams”, will be given some exceptions. The Grand Prix Commission will publish an official definition of a Claiming Rule Team in May, but a few details have been released.
Claiming Rule Teams will be given exceptions, presumably to even the playing field with the factory teams. Claiming Rule Teams will be limited to 12 engines per rider and have a fuel tank capacity of 24 liters (6.34 gallons). As the name implies, Claiming Rule Teams will likely be able to demand parts from other teams for a fixed fee. The new Moto2 class was initially supposed to have a claiming rule for engines before the commission decided to make it a spec-engine class.
