A straddle vehicle of the present invention includes: a vehicle body frame member; a rotatably supporting member supporting a front wheel; a support arm supporting the rotatably supporting member, the support arm extending rearward from the rotatably supporting member; a pair of upper and lower link members pivotally connected to the support arm at two locations on a rear portion of the support arm at least on one side of the vehicle body in a vehicle width direction, the two locations being spaced in the upward-downward direction, the pair of upper and lower link members extending rearward from the support arm, each of the link members having a rear portion pivotally connected to the vehicle body frame member; a handle; and a handle supporting member removably coupled to the vehicle body frame member and supporting the handle.

Straddle vehicle

A straddle vehicle comprises an axle; an external member which is externally fittable to the axle; and a fastening member fastened to the axle to prevent disengagement of the external member. The axle includes an outer tube member to which the external member is externally fittable, and an inner shaft member which is inserted into the outer tube member and is longer in an axial direction of the axle than the outer tube member. The inner shaft member includes a shaft part which is internally fittable to the outer tube member, a male thread part formed in an outer peripheral surface of a first end portion of the shaft part, and a retaining part protruding radially outward from a second end portion of the shaft part, the retaining part being configured to retain an axial tension of the inner shaft member generated by fastening the fastening member to the axle.

A steered wheel support structure of a vehicle, includes a knuckle member which supports an axle of a steered wheel and a support member which is coupled to a vehicle body and supports the knuckle member from a first side in a vehicle width direction in such a manner that the knuckle member is angularly displaceable around a steering axis line, the knuckle member includes: an axle support section which supports the axle; and two supported sections disposed on both sides in the upward and downward direction, of at least a portion of the axle support section, the two supported sections facing each other and being apart from each other in the upward and downward direction, and the two supported sections are supported by the support member in such a manner that the two supported sections are angularly displaceable around the steering axis line relative to the support member.

Steered wheel support structure of vehicle

A wheel for a motorcycle integrally includes a hub, a rim, and a plurality of spokes. The plurality of spokes includes a main spoke and a sub spoke extending from the hub to the main spoke. The main spoke is inclined toward a first wheel circumferential direction with respect to a straight line connecting a first coupling portion between the main spoke and the hub to a wheel rotational center, and the sub spoke is inclined toward a second wheel circumferential direction with respect to a straight line connecting a second coupling portion between the sub spoke and the hub and the wheel rotational center.

Wheel for motorcycle

A motorcycle including a multi-cylinder engine; a main frame; and a swing arm for supporting a rear wheel in a rear portion of the main frame. A rear suspension has one end rotatably supported by a portion located in a position above a swing axial support portion of the swing arm. A link mechanism connects the rear suspension and the swing arm, and includes a suspension arm rotatably supported by an upper portion of the swing arm and a link member having one end rotatably supported by the main frame. An exhaust collecting pipe is arranged below the multi-cylinder engine; and an exhaust device is arranged in a space below the swing arm. An exhaust connecting pipe connects an outlet of a rear end of the exhaust collecting pipe with a front surface of the exhaust chamber in a moving direction of the motorcycle.
