Harley-Davidson is recalling tens of thousands of motorcycles worldwide. 57,000 motorcycles have the potential for an oil line to come loose, which could lead to oil spilling into the path of the rear tire. Harley-Davidson blames the issue on an engine oil cooler line clamp not being installed correctly. The company says it knows of at least nine reports of oil lines coming off, causing two crashes and one injury. The recall affects nine 2017 Harley models built between July 2nd 2016 and May ninth of this year. Harley dealers will inspect the clamps and fix them for free.
