The FIM is taking further steps to contain the cost of aerodynamics. The banning of winglets decided earlier this year was made on two grounds: removing the danger of being struck by a protruding wing, and reducing the potentially astronomical cost of an aerodynamic war beginning.
Banning winglets would prevent the first issue from being a problem, but would do nothing to address the second point. Indeed, with the aerodynamics cat well and truly out of the bag, the factories have already hinted that their focus would switch to fairing design.
The Grand Prix Commission have moved to stop that war starting before it begins. From 2017, factories will have to homologate fairing and front mudgard designs, with only one upgrade to each allowed per season.
The idea behind it is to allow factories to continue to develop aerodynamics, but to limit the amount of time and money spent in search of wheelie prevention.
The rules do leave one loophole open, however. The aerodynamic homologation rules apply to each rider separately. In theory, each rider on a Yamaha, Honda, or Ducati could start with a different fairing, the results of which could be assessed by the factory to help develop the next homologated version of the fairing for use in mid-season.
