During the final Grand Prix Commission meeting of 2011, held on December 14 in Madrid, the following MotoGP rule changes and announcements were made, effective from January 2012.
The changes confirm the amount of tyres available in the aftermath of the MotoGP testing restrictions being lifted; that a red rear light must be displayed on all bikes in wet conditions (as in F1); that the minimum weight for next year's 1000cc bikes has been raised by 4kg and that nine CRT entries - plus one reserve - have been approved for the 2012 MotoGP season.
CRT entries have already been announced for Colin Edwards (NGM Forward Racing), Randy de Puniet (Aspar), Aleix Espargaro (Aspar), James Ellison (PBM), Anthony West (Speed Master) and Michele Pirro (Gresini).
The other three and the reserve are likely to come from Ioda Racing, BQR, Team Grillini and Team Laglisse.
These add to the twelve factory-built bikes, meaning MotoGP looks set for a grid of 21 riders next season, up from 17 (all factory built) in 2011.
