Repsol Honda will not make a debut with the pneumatic valve engine at Catalunya this weekend, but simply reserve two days of testing after the Grand Prix.

One of the reasons is the fact that Hayden and Pedrosa are not familiar with the new engine as they haven’t tested it since winter and although Tadayuki Okada made an incursion on it in Mugello and even got a 14th place, the team isn’t willing to risk anything at all.

Even more, Pedrosa isn’t willing to make a bad impression on its homeland so it’s back on the spring valve engine.

"If we were to use the engine this weekend, we would have to do comparison tests between the pneumatic-valve-spring engine and the standard engine, as well as finding the best machine set-up and choosing the correct tyres for the race.

"Also, Dani and Nicky have to achieve fast lap times to obtain the best possible grid position, so they need to concentrate on this job. It would be better to test the pneumatic-valve-spring engine during the post-race tests on Monday and Tuesday.

"After that, we will decide when to use the new engine. We will fix the earliest possible date.”
