Max Biaggi has echoed the sentiments of his World Superbike Championship rivals by claiming the hot conditions at Motorland Aragon could make the two races a lottery come Sunday.

With track temperatures reaching 60?C, many riders saw their lap times plummet after only a couple of laps, leading many to air their concerns ahead of what promises to be two very physical races.

For Biaggi, his weekend began well with the top time in FP1 before going second quickest in Q1, though the Italian concedes that he is keeping an eye on the weather.

"We started off well," he said. "Maybe we're not the absolute fastest out there, but we have a good pace. With these temperatures the main problem is tyre life, which deteriorate quickly and make it difficult to be fast over a lot of laps. In any case the conditions are difficult.

"We'll evaluate what choices to make based on the weather and track conditions tomorrow and Sunday. I like this track, so we'll see how the weekend develops."

A strong day for Aprilia, Biaggi's team-mate Eugene Laverty enjoyed his most convincing start to a weekend yet with the fourth best time, a performance that he believes could be a 'turning point'.

"This was definitely the best Friday of the season. We knew we could be fast straight away after the good test sessions last week. I really want to forget about the last three races. Aragon could very well be the turning point for my season.

"Anyway there is still a lot of room for improvement before we can aim for the podium, which is still my goal. The temperatures are definitely not normal, especially for me, so Sunday I'll be expecting two hard races."
