Abstract
A motorcycle frame includes a down tube structured to be light in weight and shaped to simplify radiator piping. The down tube extends diagonally downwards from a head pipe to a front of an engine. The down tube is formed of an angular cross section pipe, with a rib being integrally formed on a front surface inner side, extending vertically. A lower half of a rear surface section of the down tube is made into a tapered section. A space is formed between the tapered section and front sections of a cylinder head and a cylinder head cover of the engine. A water hose of a radiator and an exhaust pipe are arranged in the space.
