The World Superbike racer from Germany replaces Xavi Forés in the ERC Endurance-Ducati line-up due to Forés not being available for the Le Mans weekend from 13-16 April.
“I am happy to join ERC Endurance-Ducati,” said Öttl, who performed a similar stand-in role at last season’s 24 Heures Motos after Lorenzo Zanetti was ruled out through injury. “The Le Mans test is done and with P3 we are happy with our work so let’s do it again.”
