LONDON - Nine-time world champion Valentino Rossi Tuesday slammed MotoGP as “boring” and called for a change to the sport. “Now is the worst moment in MotoGP since I joined in 2000,” Rossi told BBC Sport. “It is the most boring moment. Races are quite bad and it is very difficult to stay awake.” Spaniards Jorge Lorenzo and Dani Pedrosa have dominated this year's championship, winning 12 out of the 16 races so far between them. Defending champion Casey Stoner, who is retiring at the age of 27 next month, is the only other rider to win this season and seven-time MotoGP champion Rossi believes the sport needs to change. He said: “You look at Moto3, the races are very exciting, Moto2 is fantastic and then MotoGP is boring. So they have to change the product.” Rossi, 33, hopes he can get back to winning ways next season with Yamaha. He won four world championships with Yamaha before leaving for Ducati at the end of 2010, but has not won in the last 37 races. “This is not the time in my career to be struggling every weekend like this,” said Rossi, who has managed just three podium finishes in his two seasons for Ducati with his last win in Malaysia in 2010. — Agencies
