Max Biaggi says he continues to be concerned by a 'vibration' problem afflicting his Aprilia RSV-4, despite posting another pair of top five finishes at the Nurburgring.
Biaggi has complained of an issue with the new bike through corners before, but admits it was proving particularly difficult around the German circuit.
His cause wasn't aided by the first day of action being washed out by rain, the Italian then being forced to work hard to get the bike set-up for dry conditions in just two sessions having had no prior data to work with.
Nonetheless, after qualifying a solid seventh, Biaggi was in contention in both races, recovering from tardy starts to end the day with a fifth and a fourth place finish.
"I am pretty satisfied, even though the conditions of these past few days were pretty difficult. Having ridden only one day on the dry track and without having any data available, our work was quite complicated, so we optimised the material we had at our disposal based on our experience in the previous races and in the end it was a good weekend.
“I still feel the usual vibrations in the turns which I'm still unable to resolve; I hope they decrease in the next races because they really limit us a lot.
“Race two went much better - a shame about the start - but we already understand where the problem came from and the pace was good. We will need more time to draw out the best in ourselves, hopefully already by Imola even though the type of circuit is not very favourable to our characteristics.”
Biaggi remains fifth in the World Superbike standings, 20 points adrift of Nurburgring winner Jonathan Rea.
