Following wet weather on day one of the Valencia post-season MotoGP test, the Factory Yamaha Team will not participate in Wednesday's second and final day.

Instead, Valentino Rossi and Jorge Lorenzo will leave Valencia this evening and take part in a one-day test at another Spanish circuit, Aragon, on Wednesday - where a Superbike test is scheduled.

While the weather forecast for Aragon is better than Valencia, there is still a chance of rain.

After two seasons at Ducati, seven time MotoGP champion Rossi made his Yamaha comeback at Valencia on Tuesday, completing 28 wet laps.

Reigning double champion Lorenzo was among seven riders that didn't record a lap time due to the conditions.

Honda and Ducati are expected to remain at Valencia for the second day.
