Ducati MotoGP boss Gigi Dall'Igna has called for a more stable set of rules for the championship as the regulations for aero packages and inertial measurement systems again come under the spotlight.

After Dall'Igna introduced aero to MotoGP in the most significant way during 2015, the rules have been changed every season and now the enigmatic Zappa-alike says enough is enough.

"Honestly, I think we have talked too much about the aerodynamics. For sure, is something new and has never exist at this level on the racing bike but we change the rules too much," said Dall'Igna, speaking at Brno.

"The stability of the rules is a must we have to keep in mind for all the rules and we change the aerodynamics rule every single year starting from 2016.

"For sure, on the safety level, aerodynamics is important on the bike and, for example an accident like Pirro at Mugello with the proper aerodynamics doesn't happen."

HRC technical boss Takeo Yokoyama is in agreement but is worried about the cash, saying he 'doesn't want to see a cost explosion.'
