Abstract
A motorcycle with a spark plug unit disposed on a front side of a cylinder head wherein approaching the spark plug unit from the front side between a front wheel and the spark plug unit as well as a high-tension cord can be prevented, without increasing the front-rear length of the vehicle. The motorcycle includes an engine with a tubular section containing a spark plug that projects roughly in a forward direction from a front surface of a cylinder head. A spark plug cap which is connected to the spark plug in the inside of the tubular section with the high-tension cord connected to a side portion thereof is fitted to the tubular section. A portion of the tubular section which projects from the cylinder head is formed with a cutout for containing the high-tension cord and for directing the cord toward a lateral side of the tubular section.
