Abstract
A vehicle, such as a motorcycle, that includes an engine air intake arrangement with a variable length intake passage. The motorcycle includes an engine having an intake port. A fixed funnel delivers air to the intake port of the engine. A moveable funnel is positioned on the intake side of the fixed funnel and selectively cooperates with the fixed funnel to deliver air to the intake port of the engine. A parallel linkage moveably supports the moveable funnel relative to the fixed funnel. An air cleaner box, in which the fixed funnel and the moveable funnel are disposed, includes a protrusion at a portion that covers the moveable funnel and that prevents the occurrence of contact with the moveable funnel.
