Into the final half of the race and Jenkner tried an over optimistic move on Stoner, clipping his rear wheel midway through a downhill right hander, sending them both tumbling through the gravel – Stoner would remount for 18th.
Meanwhile up front Cecchinello was given just the break he needed when Pedrosa, Nieto and Dovizioso held each other up as they battled for second.
That allowed Lucio to take a popular home victory by 0.7secs from Pedrosa, with Nieto just edging out Dovizioso for the final podium position.
Cecchinello's initial jubilation soon gave way to uncontrollable emotion as the now helmet-less Italian cruised into the pitlane crying his eyes out at finally achieving his dream home win.
The result leaves Cecchinello and Pedrosa tied at the top of the points heading to Barcelona next week.
