Harley-Davidson has recalled 57,000 units of its motorcycles manufactured between July 2 2016 and May 9 2017. The global recall has been initiated over possible oil leak.

Harley-Davidson says a clamp on the engine oil cooler line may not have been installed correctly. The error may cause oil line to come loose, spewing oil into the path of the rear tire.

The recall covers certain 2017 Electra Glide Ultra Classic, Police Electra Glide, Police Road King, Road King, Road King Special, Street Glide, Street Glide Special, Road Glide and Road Glide Special motorcycles. "This is a voluntary recall in the interest of customer safety," the American company said in a statement.

According to the documents posted on Friday by the US National Highway Traffic Safety Administration, nine reports of oil lines coming off have surfaced. The problem caused two crashes and one minor injury, CBS Boston reported.

Harley Davidson has also said that its dealers will inspect the clamps and fix them free of charge. The repair is expected to take about a half-hour. The Milwaukee-based company is expected to commence the recall, including about 46,000 bikes in the US, on Tuesday.

In January, Harley-Davidson suddenly shut down their York at Pennsylvania factory due to 'a critical malfunction of a clutch assembly,'  Motley Fool reported. The company had also recalled 27,000 bikes for a clutch master cylinder problem in the recent past in the US. In 2015, Harley issued a recall of the very same models affected by the new recall, though it was done for earlier versions and not the ones affected by the latest move.
