Factory Yamaha star Jorge Lorenzo feels he can increase his lead in the MotoGP World Championship over Casey Stoner at Silverstone this weekend.

Lorenzo heads the standings by 20 points following his victory at Catalunya and is confident of challenging for victory at the Northamptonshire circuit, where he stood on the top step in 2010.

A year ago, Lorenzo ran out of luck at Silverstone when he crashed out in tricky conditions as he chased Stoner, but the English circuit has traditionally been a strong venue for Yamaha and Lorenzo is optimistic he can enhance of his title credentials on Sunday.

"Silverstone is a track I like very much. In 2010 I think I did the best riding of the season, we won with a big advantage," he said.

"Unfortunately last year it rained and I crashed trying to catch Casey. Let's see if this year we can repeat the 2010 race.

"It's a track which is very positive for Yamaha so I am confident we can achieve a good result."
