Valentino Rossi and Dani Pedrosa head into this weekend's Valencia season finale with one eye already on the 2009 season, preparations for which will begin with a post-race test at the Spanish circuit.
The test will see Rossi ride an early version of the 2009 YZR-M1 and also get a better idea of the kind of tyres Bridgestone will supply to the entire MotoGP field in 2009.
"The test on Monday and Tuesday will be interesting," said Rossi. "Firstly, in the past we were lucky because usually on Monday we could sleep - after Sunday night [partying] - but this year no journalists will try the bikes and we will test from Monday morning, so for sure it will be more difficult!
"It is interesting because we have the prototype of the 2009 bike to test for the first time, after the cancelled test at Motegi, and also it is possible to try some tyres for next year's new rule," added Yamaha's 2008 world champion, who also announced that he will drive for Ford in Rally GB in early December.
Meanwhile, Pedrosa - who, like Rossi and Casey Stoner, also led the MotoGP World Championship standings this season - is looking forward to the test for similar reasons.
"Monday and Tuesday will be a very interesting test, especially for the tyre situation and some new parts for next year's bike," said the Repsol Honda rider.
"There is not so much time to rest [after the race] because, as Valentino said, before you had Monday to rest but this year the test will start straight away on Monday.
"We have some idea [about how the tyres will be next year], it is still not completely clear but I think after the race they will inform us about the new tyres," added Pedrosa, referring to the fact that the 2009 tyre regulations are still being finalised.
Stoner and Pedrosa have already been confirmed as finishing second and third in the 2008 MotoGP World Championship, but Dani is chasing a perfect hatrick of home Spanish victories this season - and his first win on Bridgestone tyres.
