Further accidents at Sachsenring's notorious Turn 11 'Waterfall' corner during practice for the German MotoGP prompted some, including Valentino Rossi, to suggest that an asymmetric front tyre should be introduced.

A series of left hand corners leads up to the Waterfall, allowing the right-hand side of the tyre to cool, exacerbating what it already a tricky, off camber and downhill, high-speed corner (pictured).

Indeed, Turn 11 is one of only three right-hand corners on the German Grand Prix circuit. However Shinji Aoki, Manager of Bridgestone's Motorsport Tyre Development Department, is doubtful asymmetric front tyres would provide a solution.

"We may investigate developing an asymmetric front slick, but good front-end feel from the motorcycle is very important to a rider feeling safe and confident, so many factors need to be considered," Aoki said.

"Having rubber of different hardness on the left and right shoulders of the front tyre can affect the feel and balance of the bike, especially under braking and changes of direction. In this case, such handling problems would outweigh any benefit so an asymmetric front tyre might not be the best solution.

"In any case, an asymmetric front tyre wouldn't solve the problems encountered at Sachsenring as the right shoulder of the tyre would still lose temperature as the distance between right-handed turns at Sachsenring is so vast.

"The layout of this circuit means that riders will always have to take extra care when negotiating right-hand corners and on Sunday they proved that there are ways to ride this circuit at a competitive pace without incident."

Aoki also pointed out that the Turn 11 accidents decreased as the weekend went on.

"The weekend started out being quite tough for some riders as the cool right side of the tyre caused by the infrequent right-hand corners resulted in a few incidents.

"However, we were always confident that our tyre allocation was up to the task and we saw that as the race weekend progressed, the pace improved and fewer incidents were recorded and Sunday passed almost without any incidents.

"This was the result of the teams, riders and Bridgestone engineers working closely together to find a bike setup and tyre combination that allowed the riders to find a good rhythm around this technical circuit."

Only two riders failed to finish Sunday's race, with no accidents at Turn 11 during the 30-lap grand prix.
