U.S. safety regulators are investigating two reports of fires in Can-Am Spyder three-wheeled motorcycles.
The probe covers about 52,000 motorcycles from the 2008 through 2014 model years.
The National Highway Traffic Safety Administration says in documents posted Friday that the fires appear to be unrelated to three recalls of the motorcycles. One Spyder was destroyed last month in a fire while being used by the Morgantown, West Virginia, Police Department. Another burned in the Mojave Desert region of California.
