The first day of unofficial World Superbike testing at Phillip Island has turned out to be an eventful one as several riders found themselves as odds with the circuit's all-new tarmac.

Resurfaced over the winter, the smoother layout of the Australian venue is expected to yield new lap records when WSBK action gets underway for official testing next week, ahead of the opening round of the season a few days later.

However, two days of 'unofficial' action is already underway with several riders being caught out by the new tarmac, including 2012 runner-up Tom Sykes and Fixi Suzuki duo Leon Camier and Jules Cluzel.

For Sykes, his accident at Siberia - partly prompted by damp patches left by an earlier storm - resulted in heavy damage to his Kawasaki.

More worryingly, the accident also left him nursing a painful wrist and while initial checks at the circuit suggested no significant damage, Sykes has since visited hospital for more thorough checks.

Camier and Cluzel, meanwhile, were unharmed, though their respective crashes did give the Crescent team plenty of repair work to do.

The accidents are likely to cause some headaches for the riders as they look to get a head-start ahead of next week's much anticipated curtain raiser.

Timing facilities were not in place for the test, but Eugene Laverty was listed as fastest from Camier and Jonathan Rea.
