Claim 12

A motorcycle comprising: (a) a motorcycle body having a longitudinal axis; (b) a motorcycle frame; (c) a head pipe fixedly mounted on a front end of said motorcycle frame and inclined rearwardly with respect to a vertical line; (d) a radiator disposed forwardly of said head pipe substantially parallel to an axis thereof and positioned in a plane lying normally to the longitudinal axis of said motorcycle body; (e) an instrument cluster unit disposed in a slanted plane extending upwardly and forwardly from above said radiator; (f) a headlight disposed in a recess defined between said instrument cluster unit and said radiator, said recess having a substantially V shape as viewed in side elevation; and (g) a fairing covering said headlight, said radiator, and said instrument cluster unit; said fairing having air inlets disposed around said headlight; said fairing including a first air guide defining a air guide passage for guiding air from said air inlets toward said radiator, said first air guide having a front end held contiguously against an inner surface of said fairing around said headlight and a rear end held contiguously against a surrounding wall surface of said radiator; and said fairing having outlet ports disposed laterally and rearwardly of said radiator, said fairing including a second air guide defining, with the inner surface of said fairing, a second air guide passage for guiding an air flow passing through said radiator toward said outlet ports, said second air guide having a wall portion of a substantially U shape as viewed in plan, which extends rearwardly from a position immediately behind said radiator along opposite inner side wall surfaces of said fairing.

Claim 13

A motorcycle according to claim 10, wherein said second air guide extends as a partition between said radiator and said fairing, and said head pipe.

Claim 14

A motorcycle comprising: (a) a motorcycle body having a longitudinal axis; (b) a motorcycle frame including a pair of down tubes; (c) a head pipe fixedly mounted on a front end of said motorcycle frame and inclined rearwardly with respect to a vertical line; (d) an upper radiator disposed forwardly of said head pipe substantially parallel to an axis thereof and positioned in a plane lying normally to the longitudinal axis of said motorcycle body; (e) an instrument cluster unit disposed in a slanted plane extending upwardly and forwardly from above said radiator; (f) a headlight disposed in a recess defined between said instrument cluster unit and said upper radiator, said recess having a substantially V shape as viewed in side elevation; (g) a fairing covering said headlight, said upper radiator, and said instrument cluster unit; (h) a single attachment frame by which said upper radiator, said instrument cluster unit, and said headlight are supported on said motorcycle frame; and (i) a lower radiator connected to said down tubes at a position below said fairing, said lower radiator communicating with said upper radiator.
