Valentino Rossi's Fiat Yamaha boss Davide Brivio has called for motorcycle racing's governing body, the FIM, to step in and sort out the crisis facing MotoGP.

The Italian reckons that the commercial aspects of the sport have been ruling for too long and it now time for technical regulations to once again be brought to the fore.

"The economic crisis, which is affecting all sectors of business worldwide, has made no exception for motor racing. Some companies are facing difficulties, although I think Kawasaki were also pressured into retirement due to a lack of results," said Brivio.

"With more success and challenge for victories they might have postponed their withdrawal or even stayed. However, this situation requires action. All the manufacturers are planning cost-saving solutions and I hope the FIM might take up an active role again, as we are all asking them to do, because maybe in recent years the commercial aspects of the sport have received too much attention compared to the technical ones.

"This is the right moment for the FIM to do more, it’s the moment for reconsidering the rules. Cost-cutting is the priority, however I don’t think anybody should panic. Some things should be changed and costs reduced and resources need to be managed well for the next two years. Also to think of how motorcycling will be in the next years is important, because this sport will go on.

"The crisis will finish, we must be positive and try to survive like everybody else, but also try to lay the bases for an even better future for this sport."

Brivio also said he things outlawing carbon brakes and reducing track time are the first things that should be considered in the effort to cut massive costs.

"There are many possible solutions, the engineers will choose which changes will allow them to save the most. We’ll all have to make an effort together. Yamaha will do its part, as it is right. Survival is our main aim, and managing resources well, but we must also think of how to improve this sport in the future."
