MotoGP bosses have added further restrictions on aerodynamic development in the class with only one fairing upgrade per rider allowed in 2017.

The move by Dorna is a ‘effort to save costs’ in the class - which allows its top stars to be paid €1M a month - and to stop aerodynamicists to create downforce inside fairings after the ban on wings.

A statement reads:

In the interests of cost saving there will be a limit on the number of upgrades that a manufacturer can make to the design of their fairing or front mudguard during the season.

Initial designs will be homologated by the Technical Director at the first event of the season. Thereafter, only one upgrade of the fairing and one upgrade of the front mudguard is permitted in that season. The restriction will apply “per rider” and not per make of motorcycle.

So much for a prototype class...
