Jochen Zeitz, the former chief executive of Puma, will temporarily take over the position of CEO and president of Harley-Davidson, the famous American brand of motorcycles. The German executive, who has been of a member of its board of directors since 2007, will hold the position until an official successor is found for Harley-Davidson’s previous CEO, Matthew Levatich. The latter has resigned but has agreed to support Zeitz until the end of March. Levatich has spent 26 years working for the brand, which has been struggling with declining sales in recent years.
