Aerodynamic symmetrical profiled element (1) for a wheeled vehicle (V) having, in cross section perpendicular to the plane of symmetry (12), at least 90% of the central part of a sage leaf profile with at least 5 arcs of circle, with a ratio between maximum spacing (E) measured perpendicular to the plane of symmetry (12) and cord (C) measured in the plane of symmetry (12) comprised between 0.1 and 0.3. Said profiled element is adapted to create a force always directed towards the leading edge (16) of the profiled element for all the resultants combining the speed of the wind and the forward speed of the vehicle.

A saddle-ride-type vehicle having a side cover for enhancing the assembling property and external appearance. In a motorcycle including a side cover which has an upper side cover and a lower side cover in a state where an end portion of the upper side cover and an end portion of the lower side cover overlap with each other, the side cover has a joining portion formed by making the upper side cover overlap with an outer side of the lower side cover. A holding portion is formed by making the lower side cover overlap with an outer side of the upper side cover. A fixing portion is provided where the upper side cover and the lower side cover are made to overlap with each other in the same overlapping state as the joining portion is disposed in the vicinity of the joining portion.

A motorcycle component adjustment member having an second side configured for mounting against a headlight of a motorcycle and an first side configured for mounting against a fairing member outer surface of a fairing member of a motorcycle. An adjustment angle is formed by the second side and the first side. The adjustment angle adjusts an angle of the headlight relative to the fairing member of the motorcycle.

A vehicle, including: a pair of front wheels; a pair of rear wheels; a saddle-style seat, positioned at an intermediate region in a width direction of the vehicle; a steering shaft provided ahead of the seat; a bar handle connected with an upper portion of the steering shaft, the bar handle having a pair of grips; a front fender provided above the pair of front wheels, striding over the pair of front wheels in a plan view of the vehicle; and a pair of suspensions, top ends of which are located ahead of the two grips, and are positioned, in the plan view of the vehicle, more inboard than widthwise ends of the two grips in the width direction of the vehicle. Each suspension includes, at an upper portion thereof, a suspension adjusting portion. The front fender includes a pair of openings through which the suspension adjusting portions are accessible.

A two-wheeled vehicle is provided including a frame, front and rear ground-engaging members each supporting the frame, a straddle-type seat, a handlebar for steering the vehicle, at least one light device configured to operate in a hazard mode, an engine supported by the frame and operably coupled to the ground-engaging members, a tilt sensor, and a vehicle control unit in communication with the tilt sensor. The vehicle control unit is operative to detect a tilt angle of the vehicle based on output from the tilt sensor. The vehicle control unit is operative to determine a tip-over condition of the vehicle based on the detected tilt angle exceeding a threshold tilt angle. The vehicle control unit activates the hazard mode of the at least one light in response to the determination of the tip-over condition.

The motorcycle includes: a supercharger that pressurizes intake air to supply the pressurized intake air to an engine; and an intake air tank forming an air intake chamber therein, which air intake chamber is provided at the downstream side of the supercharger with respect to an intake air flow direction and stores the intake air. The air intake chamber structure further includes an intake pipe formed as a separate body from the intake air tank and mounted on the intake air tank. The intake pipe serves as an inlet of the air intake chamber and projects inward of the air intake chamber. A projecting end portion of the intake pipe has a passage area that increases toward the downstream side in the intake air flow direction.
