Abstract: An assembly forming a rear fender and a chain guard for a motorcycle. The rear fender and chain guard are integrally formed and are attached to the rear swing arm suspension of the motorcycle by means of fasteners at several points.

Abstract: A back-mirror device for small-sized vehicles of the type that a back-mirror is mounted to an upper side portion of a fairing which covers a front portion of a vehicle body by the intermediary of an arm member projecting from the side portion. The arm member is provided with an opening which penetrates through the arm member in the direction of running of the vehicle, hence upon running of the vehicle, running wind blows through the opening from the forth to the rear, and thereby an air resistance is reduced. Among two arm portions separated to the above and the below by the opening, one arm portion is may be made to be able to avoid an external load by separation or bending in the event that an external load exceeding a predetermined amount is applied thereto, and the other arm portion could be provided with a flexible vibration-absorptive member.

Abstract: A body structure for a motorcycle with a front wheel and a rear wheel, including a body frame assembly having an engine mounted thereon and having vertically swingably joined thereto a front leading arm for supporting the front wheel and a rear trailing arm for supporting the rear wheel. The front leading arm as viewed from the side thereof is curved upwardly in the direction of a steering axis of the front wheel. The body frame assembly is shaped in a concave form having front standing portions and rear standing portions to thereby surround the engine. The engine is a V-type with at least a pair of internal combustion cylinders substantially vertically arranged to be respectively forwardly and rearwardly inclined, and may be secured at a front part thereof to the front standing portions of the body frame assembly and at a rear part thereof to the rear standing portions of the body frame assembly.

Abstract: A cowling device for a cycle type vehicle includes a forward unit defining a radiator air intake opening and separate removable central panels spaced from the forward unit to define a pair of side air exit openings. A relatively small amount of intake air is ducted between these central panels to the powerplant, while most is ducted alongside the vehicle through the air exit openings in a streamlined manner.
