Patent number: 7331322Abstract: An intake duct structure having an intake path extending forwardly from a cleaner box, penetrating through an area near a head pipe of a vehicle body frame, and opening at a front end portion of a front cowl. During low speed operation of the engine, an intake valve closes a main intake path MR from a front end intake port and opens a sub-intake path SR from a lower portion intake port. On the other hand, during high speed operation of the engine, the intake valve opens the main intake path MR and closes the sub-intake path SR. The lower portion intake port opens forward of a head pipe inside a front cowl and obliquely downwardly toward the rear. With this arrangement, entry of rainwater into the intake path can be minimized during low speed operation of the engine.Type: GrantFiled: March 30, 2006Date of Patent: February 19, 2008Assignee: Honda Motor Co., Ltd.Inventors: Yoshitaka Seki, Hiroshi Nakagome, Toshihisa Nagashii, Hitoshi Akaoka, Jun Hariu

Patent number: 7267193Abstract: A frame structure for a motorcycle includes a front fork which journals a front wheel and that is capable of being steered and supported by a head pipe. Front end portions of a pair of right and left pipe members are connected contiguously to the head pipe and extend downwardly and rearwardly from the head pipe. The pair of right and left pipe members each have a substantially prismatic cross sectional shape and are each bent at their longitudinally intermediate portions so as to be outwardly convex with respect to the sides of the motorcycle frame. An engine is disposed between lower portions of both pipe members in an engine mounting space. The present invention narrows the distance between the upper portions of the right and left pipe members and effectively increases the space between the lower portions of the pair of right and left pipe members.Type: GrantFiled: March 19, 2004Date of Patent: September 11, 2007Assignee: Honda Motor Co., Ltd.Inventors: Toshihisa Nagashii, Jun Hariu
