Two-time MotoGP world champion Casey Stoner will be back on the bike for Honda in 2015 – but only as a test rider.

The Australian has extended his deal with the Honda Racing Corporation (HRC) after several successful days with his former team last year.

He will begin testing in Malaysia on January 29-30 ahead of MotoGP’s first official pre-season test from February 4.

Another session will be held later in the year.

“After having a long break from riding, it was refreshing to get back on a bike a few months ago,” Stoner said.

“Now after a relaxing Christmas and New Year I’m happy to announce that I’ve been speaking to Nakamoto san (HRC executive vice president Shuhei Nakamoto) and we have come to an agreement in continuing our relationship.

“I am currently preparing to ride in Sepang in a few weeks – which will be very different weather and humidity to Motegi – so I need to get myself fit!”

Nakamoto said he was very happy to keep Stoner in the Honda family for another year.

“The feedback he gives HRC is invaluable and we are fortunate to have a test rider capable to push the RC213V to its limits,” he said in a statement.

The 29-year-old retired from MotoGP in 2012.
