Suppo fed up with allegations

Casey Stoner has won three out of four races for Ducati so far in 2007 and has been able to easily pass his rivals on the straights.

Suppo said people should give Ducati due credit for their achievements rather than suggesting that they are cheating.

"It's since Qatar - where it was even more obvious on TV - that there are these rumours," he told Italia1.

"In Qatar they checked our fuel temperature before the race and the capacity of the fuel tank after the race and everything was normal. They re-checked our fuel temperature in Turkey and everything was fine.

"So if they want to open our engine we'll be happy to oblige, because it's obviously rules-compliant. Besides it would be absolutely impossible to finish the race on 21 litres of fuel in the tank with a 1,000cc engine, so whoever spreads these rumours understands very little.

"It's a shame, because we're a small company with excellent engineers who are able to do some really commendable things.

"Obviously I'm not the right person to say it, but we're a company that makes 30,000 bikes per year and yet manages to build competitive bikes in the most important prototypes championship.

"I think it makes Italy proud. As an Italian I'm proud to be part of this team."

Suppo added that no-one had yet formally protested the Ducati, and that they were not getting any unusual attention from the officials

"There were no official complaints: the federation has the right to make random checks on the bikes," he said.

"I know at Jerez they checked the Honda engine and it was obviously okay.

"There are rules that need to be respected, without the need for someone to complain."
