SHANGHAI, May 1, 2008 (AFP) - Italian motorcycling legend Valentino Rossi aims to end a win drought at Sunday's China Moto GP but Spanish aces Jorge Lorenzo and Dani Pedrosa are set to duel for supremacy in the world standings.

The Spanish rivals lead the championship series with 61 points each ahead of the fourth race of the season at the Shanghai circuit after rookie Lorenzo scored his maiden victory last month at the Portuguese Grand Prix in Estoril.
Lorenzo, 20, off to a brilliant debut in Moto GP with three pole positions and three podiums in as many races, including a second in Qatar, would be a strong favourite had he not undergone arm surgery two weeks ago.
"The arm is really good," the double 250cc world champion said after the operation on a muscle in his right forearm.
"I'm really pleased that I will be able to ride in China, although I won't be at 100 percent, obviously," said the Mallorca native, who stepped up to the top-flight 800cc bikes this year, joining Rossi at Fiat Yamaha.
His questionable fitness will suit Pedrosa of Honda Repsol just fine as the diminutive ace from Catalonia seeks his second win of the season after a dominating performance at the Spanish GP in Jerez in March.
Seven-time world champion Rossi, third in the points standings with 47, is keen to get back to his triumphant ways as he strives to break his longest winless streak -- seven races -- since he joined the premier class in 2001.
Rossi, 29, who won the China Grand Prix in 2005 but lost a see-saw battle last year to 2007 world champion Casey Stoner of Australia, knows what it takes to master the Shanghai circuit's super-long straights and hairpins.
The mercurial five-time Moto GP champion has struggled to fine tune the Bridgestone tyres new to his Fiat Yamaha this season, but said recent modifications meant he would challenge for victory in Shanghai.
"Last year in China we weren't quite able to win, but this year our bike is working very well and, together with our tyre package, I think we should be fighting for the victory," said Rossi.
"I hope that Shanghai is going to be the place where it finally all comes together."
Rossi found himself slipping to a disappointing fifth in the season-opening Qatar Grand Prix, the first race ever held at night, but has since mounted a recovery with a second in Jerez and third in Estoril.
In China, Rossi will also have to fend off Pedrosa, who has had a sensational early 2008 with three podiums of his own, including a second in Portugal and third in Qatar.
The 22-year-old Spaniard is also no stranger to the demands of the ultra-modern Shanghai circuit, taking top honours in 2006 and fourth last year.
"One of the most important parts of the track is the back straight, which is very long, so you need good engine performance here," the former 125cc and 250cc world champion told reporters.
"Braking is also very important at Shanghai. It's an unusual track and you need to ride relaxed and easy."
But given Shanghai's two ultra-long straights, Pedrosa will have to rely on his bike's nimble handling if he is to beat the Yamaha and Ducati bikes, which reign supreme in a straight line.
Stoner's Ducati Marlboro is especially powerful and although the Southport native has experienced a dip in pace since his season-opening victory in Qatar, and sits fourth in the standings with 40 points, he will be eager to get back on form.
