The front fairing (14) is so formed as to bulge gradually laterally and upwardly of the vehicle widthwise direction from a tip portion (14a) in a rearward direction, and the headlight device (18) is disposed proximate to a lower end of the front fairing (14).

Abstract: A cooling structure of a piston in an engine, in which oil is injected toward a top portion of the piston reciprocating within a cylinder of the engine to cool the top portion of the engine. The cooling structure may include an oil guide surface including at least a thick wall portion of a peripheral wall of the piston which is provided with a ring groove and extends continuously from an inner surface of the peripheral wall of the piston to a reverse surface of the top portion of the piston.

Abstract: An attachment structure for a resin part of a motorcycle includes an attaching portion with a nut on a vehicle main body, an attached portion of the resin part having a bolt insertion hole, and a shoulder bolt, wherein the shoulder bolt has a large diameter portion thicker than an threaded shaft portion, the bolt insertion hole has an inner diameter into which the large diameter portion is insertable, and a thin guide piece protruding toward a radially inner side for regulating radial movement of the shoulder bolt within a predetermined range is integrally formed on an inner circumferential surface of the bolt insertion hole.

Abstract: The present invention provides a meter display device provided in a vehicle, including a display portion having a display region in which a plurality of display areas extending elongatedly in the left-right direction of a meter body are provided in proximity in a line arrangement in the orthogonal direction orthogonal to the left-right direction, and a display control portion switching each of the display areas between the display operated state and the non-display operated state and increasing the number of the display areas display-operated.

Abstract: A fuel tank which has partition walls capable of flowing fuel into a fuel suction port more easily at the time of the acceleration/deceleration of a vehicle is provided. A fuel tank 11 for vehicle has a fuel suction port 22 through which a fuel pump sucks fuel in the fuel tank 11 from the lower portion of the inner space of the fuel tank 11, a first partition wall 31 surrounding one of the front and and the rear and the sides of the fuel suction port 22 to have an opening to the other of the front and the rear and preventing the fuel from moving to one of the front and the rear, and a second partition wall 32 surrounding the sides and the other of the front and the rear of the first partition wall 31 to have an opening to one of the front and the rear and preventing the fuel from moving to the other of the front and the rear.

Abstract: The present invention is to provide an attachment structure for a windshield capable of more easily manually changing a position of the windshield. In an attachment structure for a windshield 17 provided in an upper part of a vehicle body front part of a vehicle 1 for easing wind pressure to a driver, including a plate 21 attached the windshield 17, a shield stay 18 attached to a vehicle body, and a clamp 30 capable of fastening the plate 21 and the shield stay 18 from the front and rear sides, the clamp 30 includes an operation portion 31 capable of manually operating fastening and fastening cancellation, and by operating the operation portion 31 so as to cancel the fastening of the clamp 30, the plate 21 is movable upward and downward along the shield stay 18.

Abstract: An exhaust muffler for silencing exhaust gases, introduced from a first side, and then discharging them to a second side opposite to the first side, includes a silencing chamber forming structure having first, second and third chambers disposed sequentially from the second side to the first side, an inlet tube to communicate the outside on the first side with the first chamber after having sequentially passed through the third and second chambers, an outlet tube to communicate the second chamber with the outside on the second side after having passed through the first chamber, a first communicating passage communicating between the first and second chambers, and a second communicating passage communicating between the second and third chambers. A peripheral wall portion of the inlet tube, positioned in the third chamber, is formed with a vent hole to communicate a space within the inlet tube with the third chamber.

Abstract: An air guiding structure introduces a cooling air to be supplied to a radiator, positioned forwardly of a combustion engine, and an engine intake air from a single opening in a fairing. The fairing encloses at least an area forwardly of a head pipe and an area laterally outwardly of the radiator. A portion of an inner peripheral face of the opening is formed by an inner cowl. An intake air inlet for introducing the engine intake air is disposed above the radiator. The inner cowl is extended rearwardly to form a cowl extension confronting at least a lower portion of the head pipe and a lower bracket of a front fork assembly from outside. A side wall of the inner cowl including the cowl extension is formed with a guide for guiding an incoming air towards the intake air inlet.
