The Grand Prix Commission held a meeting on 17 February in Barcelona, unanimously deciding to introduce a number of revisions to the Road Racing World Championship Grand Prix Regulations for this year’s MotoGP world series.

Composed of Carmelo Ezpeleta (Dorna, Chairman), Claude Danis (FIM), Hervé Poncharal (IRTA) and Takanao Tsubouchi (MSMA), in the presence of Ignacio Verneda (FIM Sports Director), Javier Alonso (Dorna) and M. Paul Butler (Secretary of the meeting), it was decided that the following changes will be put in place.

Tyre temperature or tyre pressure sensors are not permitted.

Racing number must be affixed to the front and the two sides of the motorcycle. For the MotoGP and Moto2 classes, only the front number is compulsory.

In the Moto2 category, the engine performance, as measured by the official supplier under their standard dynamometer conditions, must be within the tolerance range agreed by the organiser and the official supplier.

A team may request a replacement engine on the grounds of substandard performance. Such request must be made in writing to the Technical Director accompanied by a deposit of €20,000 per engine paid to IRTA. If the Technical Director is satisfied that there is clear evidence of substandard performance a replacement engine may be issued with the approval of the Race Direction for the next race event.

The original engine will be returned to the official Supplier at the end of the race event where the complaint is lodged to be tested under standard conditions by the official Supplier and the dynamometer report sent to the Technical Director.

If the engine is deemed within specified performance parameters and fit for use, the same engine will be returned to the team for the following race and the team’s deposit will be forfeited. If the engine is deemed to be outside of specified performance parameters and not fit for use, a replacement engine will be issued for the next race and the deposit will be returned to the team in full.

There have also been additional technical specifications for 2012 for the MotoGP class released, confirming that there will be a maximum displacement of 1000cc for four-cylinder engines at 81mm.

It’s also been confirmed that 800cc engines will remain with a maximum weight limit 150kg, while over 800cc engines will have to weigh 153kg.

Fuel tank capacities for both the 800cc and 1000cc engines will be 21 litres.

There will be a maximum number of six engines available for use by each rider.

A unique rule as an exception for Claiming Rule Teams (CRT’s) approved by the Grand Prix Commission will be that they’ll be abl eto use 12 engines and have a fuel tank capacity of 24 litres.

The definition of the CRT will be published by the end of May.
