Max Biaggi says he was forced to call upon his copious experience in order to seal a potentially crucial fourth World Superbike Championship win of the season at Motorland Aragon, the Italian multiplying his series lead to 48 points in the process.

Coming into the weekend with a comfortable advantage having triumphed in both races at Misano, Biaggi carried that form to the first Aragon race as he diced with countryman Marco Melandri in an encounter not dissimilar to that of 12 months ago around the same venue.

Though Melandri twice managed to get his BMW ahead of the Aprilia, Biaggi struck back decisively with less than two laps remaining to seal a hard fought fourth win of the year.

"We certainly didn't hold anything back," he said. "We were basically all in the same conditions, so there was no way to make the difference. I really had to give 100 per cent, especially after the halfway point when the tyres started to lose grip and I had to be careful not to make any mistakes.

"After overtaking the last time in race one, the decisive overtake, I gained a few metres advantage and managed to win."

Going on to finish the second race in fourth after losing out in the four-way scrap for the lead with Melandri, Eugene Laverty and Chaz Davies, Biaggi has nonetheless boosted his advantage in the overall standings to 48 points, now over Melandri.
