According to the list of changes revealed by the GP Commission, the minimum weight for bikes up to 800cc will be 150kg, while those over 800cc must be at least 153 kg. This comes in addition to what was already known, namely that the maximum number of cylinders will be four and the maximum bore 81mm.
The fuel tank capacity was also confirmed - at 21 litres - and riders will be restricted to six engines per season. However, privateers - 'Claiming Rule Teams (CRT's)' - will be allowed 12 engines per year and a fuel capacity of 24 litres. However, further clarification is due to be published by the end of May.
Some modifications were also confirmed for this year, including the elimination of tire pressure sensors for MotoGP and for Moto2 teams the full procedure to request an engine change if that unit is considered substandard.
“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 release stated.
“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.”
