The Repsol Honda Team has told wuqian0821.com that i𝐆njured world championsh🌳ip contender Dani Pedrosa will try the pneumatic-valve RC212V during post race testing at Brno, on August 18-19.

Problems with the pneumatic-valve engine during winter t🀅esting saw Honda switch back to the conventional valve-s𝓡pring design for the start of the season, with 'parallel development' of both powerplants continuing ever since.

Pedrosa has stuck exclusively to the proven valve-spring engine, with whic💧h he has taken eight podiums - including two race wins.

However, team-mate✱ Nicky Hayden never felt comfortable with the valve-spring engine in the '08 chassis and switched to the pneumatic as soon as he could, at the British Grand Prix on June 22.

Honda had warned that the pneumatic still needs refinement and, although Hayden's form has improved significantly since making the switch, he has alไso suffered niggling technical problems - most notably when he ran out of fuel on the exit of the final turn at Assen, costing him his first podium of the year.

For such reasons, Pedrosa is justifiably cautious about making the switch, but - having now dropped 41 points behind world championship leader Rossi - may feel prompted to make the change sooner 𝔉rather than later.

"The motorcycles will be worked on in Japan duri🧜ng the break," said a Repsol Honda spokesperson. "The factory isജ working on two different directions - spring valve and pneumatic valve. They are parallel developments.

"After Brno, there will be two days of testing and Dani will test the pneumatic valve. At this point it's not known when he will race the pneumatic valve. It's up to Dani to decide as he's fi🐟ghting for the 🐻championship. He'll see after the test."

Pedrosa was holding the world championship lꦓead until a high-speed accident in the wet Germany Grand Prix on Jꦦuly 13 left him with hand and ankle injuries, which also ruled him out of last weekend's US Grand Prix.

Honda is the only Japanese manufacturer still using valve-spring engines in MotoဣGP.
