Abstract
A vehicle, such as a motorcycle, having an arrangement that inhibits the reduction of the fuel tank volume disposed to the rear of a moveable funnel that forms a portion of a variable length air intake. The vehicle includes an engine having an intake port. A fixed funnel introduces air to the intake port of the engine and a moveable funnel is position on the inlet side of the fixed funnel to selectively cooperate with the fixed funnel to deliver air to the intake port of the engine along with the fixed funnel. A parallel linkage moveably supports the moveable funnel. A fuel tank is disposed to the rear side of the moveable funnel and a motor that drives the parallel linkage is disposed on the opposite side to the fuel tank from the moveable funnel.
