Former 250cc racer Alex Debon will join the coaching team of Ducati MotoGP rider Jorge Lorenzo for 2018.
Debon, 41, made 152 starts in the 250cc/Moto2 category between 1998 and 2010, scoring two grand prix victories and a best championship placing of fourth in 2008.
He was also test rider for Aprilia's 250cc project in 2006 and 2007, with Lorenzo winning the title both years under the leadership of Ducati's current technical boss, Gigi Dall'Igna.
Debon has already started working with Lorenzo, joining the Spaniard's entourage in last month's Valencia and Jerez post-season tests.
Ducati test rider Michele Pirro was assigned to Lorenzo as a coach this year, but the Italian's wildcard races and CIV Superbike commitments prevented him from performing his duties at some events.
On the other hand, Debon will be present at every race in 2018.
