A vehicle body frame structure for a saddle riding type vehicle, the vehicle body frame structure includes main frames formed by coupling main tubes extending rearwardly downward from a head pipe supporting a front wheel via a front fork to pivot frames supporting a rear fork by rear end portions of the pivot frames, and a rear frame in a rear of the main frames, the rear frame being formed of a fiber reinforced resin and supporting a seat. The rear frame includes upper side attaching portions attached to the main frames, a pair of left and right upper side portions linearly extending rearward from the upper side attaching portions, and a cross member laterally coupling the upper side portions to each other. The cross member includes a bulging portion bulging above the upper side portions.

A rear frame is formed of a laminate that includes a plurality of carbon fiber layers laminated one on top of another and hardened and integrated with each other by a plastic. A different color layer having a color different from a color of the carbon fiber layers is disposed between the carbon fiber layers in the laminate. When a carbon fiber layer on the outside is lost by a piece of flying gravel and a lost portion reaches the different color layer, a surface of the different color layer is exposed from the lost portion. An exposed portion having the different color can be easily recognized from the outside. The appearance of the exposed portion allows arrival of a replacement time of the rear frame to be recognized. As a result, it is possible to enable easy visual recognition of an optimum replacement timing.

Exterior part of saddled vehicle

To provide an engine side cover structure of a saddle type vehicle that can also cover the back side of a crankcase. An engine side cover structure of a saddle type vehicle includes a vehicle body frame arranged between a front wheel and a rear wheel; an engine including a crankcase, and a cylinder extending upward from the crankcase, the engine being supported by the vehicle body frame; and a side cover covering a side of the crankcase; where the side cover includes a cover main body that covers the side of the crankcase, and an extended portion that extends backward from the cover main body; and the cover main body is fixed to the crankcase, and the extended portion is fixed to the vehicle body frame.

Engine side cover structure of saddle type vehicle

A handling performance is improved by a fuel tank fitting structure. A fuel tank is mounted to a vehicle body frame at three points: a first fixed section with a bolt and two second fixed sections with two bolts. A grommet provided in the first fixed section has an interference. Each of the second fixed sections has a fitting clearance between a collar and the grommet, and an axial clearance between the collar and the grommet. These clearances enable the grommet without an interference and the fuel tank to relatively movable to the vehicle body frame. The fuel tank and a vehicle body thus have different behaviors during cornering, thereby obtaining reduced inertial weight and light handling.

Saddle type vehicle

In the electric component support structure for the saddle ride vehicle including a body frame F that supports a water-cooled engine, and a radiator that is supported on the body frame through collars, a gyro sensor is fixed to electric component support pieces provided on the radiator.

Electric component support structure for saddle ride vehicle

Inside a radiator shroud covering an outside of an engine or an outside of a radiator supposed to get hot relating to the engine, a first protruding portion and a second protruding portion are provided. An abutting surface to abut on the engine or the radiator is provided at a distal end of each of the first protruding portion and the second protruding portion. The first protruding portion and the second protruding portion are made of resin material with higher heat resistance than a shroud body of the radiator shroud.

Body cover structure for saddle riding vehicle

An air cleaner is disposed at the front part of an intake space below a seat. A battery box containing a battery is disposed on the rear side relative to the air cleaner in the intake space. The battery box is disposed with a rearward tilt and on the intake upstream side of the air cleaner and a corner part of the battery box at the lower front end thereof is disposed close to the air cleaner with the intermediary of a slight gap. The battery in the battery box is located in a flow of intake air sucked into the air cleaner and is efficiently cooled. The battery box includes an opening wherein part of the outer surface of the battery and a degassing part face the opening. An anti-diffusion cover part, continuous with an edge of the opening, covers the degassing part.

A saddle-ride-type vehicle includes a vehicle body lower portion protective member for increasing the rigidity thereof and for protecting a vehicle body frame. A saddle-ride type vehicle includes a head pipe and a pair of left and right lower frames extending from the head pipe for supporting an engine. An engine guard extends from an area in front of the engine to an area below the engine. The engine guard includes an engine protective portion for covering the engine and a frame protective portion for protecting the lower frame. The engine protective portion and the frame protective portion are disposed with a step formed therebetween.

Saddle-ride type vehicle

A vehicle body frame for a saddle-ride type vehicle is manufactured by laser welding, and has good dimensional accuracy in a vehicle length direction. A pivot frame includes a grooved member, a lid member put on an opening of the grooved member, and laser-weld beads with which this lid member is joined to the grooved member. The molten metal shrinks during its solidification, and shrinkage occurs in the vehicle width direction. However, no shrinkage occurs in the vehicle longitudinal direction. As a result, the distance between a head pipe and a pivot shaft is maintained properly.

A saddle riding type vehicle, includes a frame including a head pipe and a pair of left and right main frames extending rearward and downward from the head pip, a fuel tank supported between the left and right main frames, a radiator; and a radiator shroud structure. The shroud structure includes shrouds covering lateral sides of the radiator and shroud fastening portions fixed to outer side walls of the left and right main frames so that upper portions of the shrouds are arranged in covering relation along outer faces of the outer side walls of the main frames, and lower portions of the shrouds extend downward from the upper portions of the shrouds and are connected to the radiator.

To provide a vehicle body frame for a motorcycle which includes a head pipe having good dimensional accuracy. A head pipe includes a left half which is obtained by die forming, a right half which is obtained by die forming, and beads with which the right half is integrated with the left half by laser welding. The head pipe is formed by joining the left half and the right half to each other with the first and second beads which are laser weld beads. Laser weld beads are significantly smaller in bead width than arc weld beads, and therefore their shrinkage after their solidification is significantly smaller. As a result, a head pipe having good dimensional accuracy is obtained.

A vehicle body frame manufactured by welding is configured for weight reduction, and includes first and second frame members. The first frame member has a predetermined thickness including a first flat surface portion wider than the predetermined thickness. The second frame member includes a second flat surface portion touching the first flat surface portion. The first and second frame members are joined by bringing the flat surface portions together and welding the first and second flat surface portions together with laser beams parallel to the first flat surface portion. In this way, the laser welding can be performed with a reduced gap between the two members. Welding using laser beams applied from directions parallel to the flat surfaces allows the weld area to be significantly larger than conventional fillet welding.

An exhaust device of an internal combustion engine for reducing exhaust sound and for suppressing the occurrence of a torque valley. A sound-deadening and pressure-dissipating device connected to the downstream end of an exhaust pipe includes a spherical member having an opening portion opening toward a downstream edge of the exhaust pipe. Exhaust gas from the exhaust pipe is reflected by an inner spherical surface of the spherical member to reduce exhaust pressure in the spherical member and then is discharged from the opening portion.
