Abstract
A compact air cleaner for a motorcycle engine has its intake duct directed in a widthwise direction of the motorcycle. The air cleaner includes an air cleaner case, an air cleaner element and a case cover. The air cleaner element partitions an inner portion of the air cleaner case and case cover into a clean room and a dirty room. The air cleaner element extends in the motorcycle's travel direction. An intake port communicates with the dirty room and opens to a space surrounded by a rear face of the clean room, a front portion of a rear fender and a bottom portion of a seat.
