Casey Stoner is set to complete his first Ducati MotoGP laps since 2010 at Sepang on January 30.
According to GPOne.com
the retired double world champion will test for two days at the Malaysian circuit using this year's GP15 machine, the Australian apparently requesting to try the older bike first.
The new Desmosedici will then be used by Andrea Iannone and Andrea Dovizioso during the official Sepang test, to be attended by all race riders, from February 1-3.
Stoner has taken part in sporadic tests for Honda since leaving MotoGP at the end of 2012, but was recently announced as a brand ambassador and test rider for Ducati.
The 30-year-old won Ducati's only MotoGP title in 2007 and claimed the factory's most recent race win at Phillip Island 2010.
Having offered to replace the injured Dani Pedrosa earlier this year, MotoGP fans will hope Stoner can be tempted to make some wild-card appearances for Ducati next season...
