Aleix Espargaro has his heart set on changing machinery for the 2014 MotoGP season.
Espargaro has dominated the privateer CRT class for the Aspar team since its 2012 creation.
Aspar has an option on Espargaro for 2014, when Aprilia plans to significantly upgrade its ART motorcycle, but that is not enough to convince the Spaniard to stay.
Instead, Espargaro has his sights set on racing the new privateer Yamaha M1 package at the Forward Racing team.
"I have motivation to change bike," confirmed Espargaro, who has scored over twice as many points as the next best CRT rider this year. "I'm doing a big effort to move but it's not easy. Both teams are in talks. I think we are close, but still nothing is decided. I hope in a couple of days we will have some news."
Espargaro made clear that he has nothing against the Aspar squad.
"I feel really good at this [Aspar] team, I really don't want to go away because it is like a family. I'm really comfortable. But sometimes you have motivation to ride another bike and in this case I feel that the other bike is maybe more competitive.
"You never know, but sometimes you need to find your motivation and you need to choose your future. It doesn't matter if finally it will be good or not... Yeah I really want to change the bike."
Departing Ducati star Nicky Hayden
is tipped to take Espargaro's place at Aspar Aprilia, with Espargaro likely to join present Forward rider Colin Edwards
once negotiations are complete.
Both Espargaro brothers thus look set to be on Yamaha machinery in MotoGP next year, with younger brother Pol stepping up from Moto2 to ride for the Monster Yamaha Tech 3 team. Pol is currently fighting Scott Redding for the 600cc crown.
"I'm more tired when he's racing than when I race!" smiled Aleix. "He is doing a really, really good season, but also Scott is really strong. Misano was a very good race for Pol but he is still far away, 23 points and just five races.
"It will not be easy but I hope Pol will push. He lost against Marc [Marquez] in 125cc and again in Moto2. This is the third time he is battling for a title and I hope he can win this year."
Forward Racing currently uses FTR-Kawasaki machinery.
