A motorcycle includes a fuel tank mounted on a main frame member, an engine arranged below the main frame member, and ignition coils arranged below the fuel tank. The main frame member includes a pair of sub-frame members arranged in a vehicle-width direction in a spaced-apart manner. A coil-holding structure, formed of a plastic resin material, is disposed on the main frame member for arranging the ignition coils thereon between the pair of sub-frame members. A base portion of the coil-holding structure has one or more openings formed therein so as to expose portions of the ignition coils to a traveling wind, during vehicle operation. One of the ignition coils, which is arranged close to a rear side of a vehicle body, is disposed at a position lower than a position of the ignition coil which is arranged close to a front side of the vehicle body.
