Dani Pedrosa has denied that he has signed a new MotoGP contract with Honda, but did reveal that he will try a modified chassis during this weekend's Grand Prix of Catalunya.

The Spaniard has been a factory Repsol Honda rider ever since his 2006 MotoGP debut and is the only Honda rider to win a race since the switch to 800cc engines.

Pedrosa has won two races a year since joining the premier class with a best championship ranking of second, a distant 125 points behind Casey Stoner, in 2007.

But the 125 and double 250cc world champion is yet to mount a sustained title attack and has appeared increasingly frustrated at the lack of progress with Honda's RC212V project.

Rumours had also circulated that Repsol might try to sign fellow Spaniard Jorge Lorenzo to replace Pedrosa, but those looked to have died down and Pedrosa remaining at Repsol Honda seems the most likely scenario.

Nevertheless, pressed on whether rumours that he had signed a new contract with Honda for 2010 were true Pedrosa responded: "We have not even had that conversation yet."

Pedrosa, who will ride with the aid of pain-killing injections this weekend after cracking his thigh last time out at Mugello, did confirm that he will try a modified chassis in Catalunya, as Honda fights to adapt the RC212V to the new single-tyre rule.

"We have something which, if the conditions are good, we will try straight away this weekend," he said. "It is a modified frame to improve the stability under braking. That is the main target and we will check how it works. If I can handle the pain then I will also take part in the test on Monday."

Pedrosa will start round six of the 2009 world championship in fourth position, 33 points behind Stoner.
