A frame of a motorcycle includes a head pipe configured to support a steering shaft, a first frame configured to extend from the head pipe, through above and rearward of an engine, and to rearward of a vehicle body, a second frame that is located under the first frame and configured to extend from the head pipe, through forward and downward of the engine, and to rearward of the vehicle body, a bracket by which a first component is mounted to the second frame, and a coupling member that is mounted to the second frame to couple a second component to the second frame, and the bracket is integral with the coupling member. An engine bracket of a motorcycle is manufactured by forging such that a region subjected to tensile stress is made thicker than a region in the vicinity of the region which is subjected to the tensile stress.

Frame of motorcycle and engine bracket

A shroud, typically of an off-road motorcycle is provided. The motorcycle includes a fuel tank provided in an upper front portion of the motorcycle body. The shroud structure includes an upper shroud that extends along a side face of the fuel tank and covers the fuel tank, and a lower shroud disposed below the upper shroud. The upper and lower shrouds are detachably coupled to each other.

Shroud of a vehicle

A body frame of a two-wheeled vehicle. The body frame typically includes a head pipe to which a steering shaft extending substantially vertically is rotatably mounted. The head pipe includes an upper head pipe and a lower head pipe that are configured to be molded and to be coupled to each other. The upper head pipe includes an upper tubular portion into which the steering shaft is inserted and a main frame tongue portion that is configured to extend rearward from the upper tubular portion and is configured to support a front portion of the main frame from above. The lower head pipe includes a lower tubular portion into which the steering shaft is inserted and a down tube tongue portion that is configured to extend downward from the lower tubular portion and to support an upper portion of the down tube from forward.

The present invention provides a watercraft having steering components (steering tabs or stabilizers) for maintaining steering capability even while amount of water ejected from a propulsion pump is decreased. The steering components are movably disposed on a hull of the watercraft at or below the water level on both right and left sides to be in an &ldquo;Operating State&rdquo; in which resistance of water is larger or to be in a &ldquo;Non-operating State&rdquo; in which the resistance of water is smaller in accordance with steering operation. Furthermore, a mechanism for absorbing an external force acting on the steering components in the &ldquo;Operating State&rdquo; is located in a system for operating the steering components. The mechanism reacts to the external force to allow the steering components to be transformed into the &ldquo;Non-operating State.&rdquo;

Watercraft

An inner frame member, of a length that is less than the entire length of a hull, is joined to the inner surface of the hull that forms a lower portion of a body of a personal watercraft. The inner frame member has an engine mount portion that supports an engine thereon, an impeller shaft support region that supports thereon an impeller shaft of a propulsion device driven by the engine, and bulkheads extending in the lateral direction of the hull and joined to the inner surface of the hull. In accordance with the present invention, the personal watercraft is light weight, but also retains rigidity and assembling efficiency of the hull.

Personal watercraft

Provided is a hull shape of a personal watercraft which can enhance speed performance, and still more, can also reduce rolling of a body. A bulging face,is formed on an outside part of a rear portion of a hull bottom,having a substantially V-shaped cross section and protrudes downward from an outside front face,positioned in front of the outside part. The bulging face,includes a fore part,inclined downward in the rearward direction, and a rear part,positioned above a virtual face A extended rearwardly from the fore part

Hull shape of personal watercraft

Provided is an oil feeding structure of a personal watercraft capable of enhancing the appearance design of the personal watercraft and of readily letting air out of a tank during oil feeding, thereby smoothly feeding oil. A surface,inclined outward and downward is formed on both sides of the highest portion on a deck,, that is, a portion between a housing portion B for a storage box,and a housing portion S for a steering mechanism. Oil feeding ports,and,are formed on the inclined surfaces, respectively. First and second oil feeding pipe members,and,are arranged downward in a substantially vertical direction from the oil feeding ports,and,, and are connected to a fuel tank,and a lubricating oil tank,substantially rectilinearly, respectively.

Oil feeding structure of personal watercraft

A bottom structure of a personal watercraft enhances the running performance of a personal watercraft. A concavo-convex face (,) having very small concave or convex portions for drawing air from an outside of a watercraft is formed on a water contact face (S) in a bottom surface (,) of the personal watercraft during planing. The air is drawn by the concavo-convex face (,), thereby separating a water flow from the bottom surface (,). Consequently, frictional resistance to the water in the bottom surface (,) can be reduced.
