Texan Ben Spies is praying for a change of luck at Silverstone this weekend after crashing out while battling for the lead at Catalunya.

Spies looked set to put his season back on track after a lacklustre string of results, but bit the dust after passing Repsol Honda's Dani Pedrosa.

He remounted and battled back to finish tenth, although it could have been so much better for the factory Yamaha star.

Spies' apparent rejuvenation continued during the MotoGP test at Aragon, where he was narrowly edged out at the top of the times by team-mate Jorge Lorenzo, albeit in the absence of factory Honda men Casey Stoner and Dani Pedrosa.

Last year, he slipped off in the treacherous conditions at Silverstone, but the American achieved his first MotoGP podium in 2010 when the championship returned to the historic British circuit for the first time since 1986.

"I'm really looking forward to getting back on the bike as soon as possible," he said.

"We had a good test in Spain and apart from the crash in Barcelona we were really competitive with a great bike.

"I think Silverstone will be really good for the Yamaha so I'm hoping to get the set up right as quickly as possible with the guys and focus on delivering a good result on Sunday," added Spies.

"I really like the track and it's obviously special for me as it's where I got my first MotoGP podium."
