The intense demands of the Monza circuit took their toll on the Foggy PETRONAS Racing team as Steve Martin and Craig Jones were unable to complete a race.

Mechanical problems which had been evident during the two days of qualifying persisted on race day, while championship leader Troy Bayliss romped to victory in both contests to extend his championship lead.

Team manager Jack Valentine said: "Monza has always been a tough circuit for us and the nature of the circuit again has highlighted some of the weaknesses that persist with a bike which is still continually being developed. We will get to work on solutions straight away to ensure that we are in better shape for the next round at Silverstone."

Jones and Martin stayed clear of the first race carnage at the first chicane, where seven riders crashed, leaving Craig in 14th place going into the first split before he pulled in with an electrical problem, shortly before Martin retired with an oil leak.

And, on a day littered with a total of 19 retirements, the second race was equally short as Jones, running a new gearbox, ran off into the gravel and Martin had to pull in with further mechanical issues.
