Harley-Davidson has confirmed a National Highway Transportation Safety Administration recall notice on just under 46,000 of its big-bore road machines.
NHTSA reported Friday that Harley had recalled some 2014 and 2015 models of its Electra Glide, Street Glide, Ultra Limited, Road Glide and Road King motorcycles.
The affected motorcycles have potentially defective clutch master cylinders that may fail to fully disengage the clutch when the machines are in gear -- especially if they have been parked "for an extended period of time," the federal agency said -- increasing the risk of a crash.
Some accidents and minor injuries have been associated with the defect, but no fatalities.
The Milwaukee-based motorcycle manufacturer -- the country's largest -- said in confirming the recall notice that it wanted to extend an apology to Harley riders.
"First and foremost, we apologize to our customers for this issue," the company said in a statement. "We're riders, too, so share in the frustration. Customer safety is our first priority."
The NHTSA notice said that Harley will begin notifying owners of the affected motorcycles, and alert dealers to perform free service checks to flush the clutch systems and rebuild the defective master cylinders.
Those notices will begin going out April 23, the NHTSA said.
